Don’t Be Blunt: A Practical Knife Sharpening Reference


If you’ve ever spent some quality time in a kitchen or out in the great outdoors, you’ll know there’s nothing quite like the feel of a sharp knife in your hand. Besides getting those clean cuts, having a sharp blade makes your job safer, needs less muscle, and gives you better control, slashing the chances of any mishaps.

Whether you’re chopping veggies for a backyard barbecue, slicing up some brisket for a tailgate, or cutting through tougher stuff during a camping trip in the Smokies, a good sharp knife can make all the difference.

And let’s talk about the joy of cooking—especially here in Nashville, where food is almost a religion. It’s so much more satisfying to prepare a meal when your knife slides right through whatever you’re cutting, rather than having to wrestle with it. For any chef or weekend grill master, having sharp knives can transform everyday meal prep into a much smoother (and much more fun) process.

Sharpening your blades not only makes cutting easier, but it also extends their life—saving you money and the trouble of frequent replacements. And, of course, a truly sharp knife requires less force to cut, reducing the risk of slipping and potential injury.

Before we get started, let’s go over some important things to keep in mind and a disclaimer:

  3. Inattention during sharpening can lead to unexpected mishaps. A dull blade can easily slip and cause an accident, something we all want to avoid. So, remember to keep both your blades and your wits sharp.
  4. Not to be blunt—pun very much intended—but if you are unsure at all about your sharpening skills or don’t feel confident in your ability to maintain your knives safely, don’t hesitate to seek out a professional knife/blade sharpening service.

Disclaimer: This article provides general information about knife sharpening techniques and tools aimed at helping readers learn more about maintaining their blades. Of course, blade sharpening involves certain risks, including potential injury. The steps and tips provided are suggestions based on general practices. However, individual results may vary. For high-end or specialized blades, or if you are unsure about the process, we highly recommend seeking professional knife sharpening services near you. Always prioritize safety, using appropriate safety gear, and consider leaving blade sharpening to the professionals.

With that out of the way, let’s take a closer look at three of the most common types of knife edges and the care they require to maintain their sharpness.

Knife Edges

Before we can discuss knife sharpening in detail, we need to talk a bit about the anatomy of a knife. The edge of a knife is where all the action happens, and knowing a bit about how they’re shaped can help you keep them in good shape—literally.

Knives come with different types of edges, each designed for specific tasks. The most common ones you’ll run into are straight edges, serrated edges, and hollow edges.

Here’s what you need to know about each:

Straight Edges

Straight-edged knives are the most commonly used knives in both professional kitchens and home cooking setups. These knives feature a continuous sharp edge that is free from serrations or indentations.

These are your all-purpose edges, found on most chef knives and utility blades. They’re designed for clean, precise cuts. A straight-edged knife can handle everything from chopping onions to mincing herbs.

Due to their straightforward design, straight-edged knives are among the easier types to sharpen, accommodating a variety of sharpening tools and techniques which can efficiently restore their sharpness. However, achieving a perfectly sharp edge still requires skill and attention.

Various sharpening tools, from whetstones to guided sharpening systems, can be used to restore and maintain their sharpness, each requiring a certain level of technique and practice to use effectively.

Serrated Edges

Think of your classic bread knife. Serrated knives have a wavy, tooth-like edge that’s perfect for cutting through tougher exteriors and soft interiors—like slicing through a crusty loaf of bread without completely crushing it.

Unlike straight-edged knives that offer a continuous edge, serrated knives require sharpening each individual serration. Each “tooth” must be sharpened individually, which demands precision and the correct tool, such as a tapered or rod-shaped sharpener that can fit into the serrations.

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

Improper sharpening can easily damage a serrated knife. The unique shape of the serrations means that using the wrong technique or tool can wear down the teeth unevenly or flatten the serrations, thereby ruining the knife’s cutting ability.

The sharpening process for serrated blades is not only meticulous but also requires a bit more skill and understanding of the blade’s geometry than sharpening a straight edge. Even with the right tools, achieving a consistent sharpness across all serrations without professional training can be extremely challenging.

Hollow Edges

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

Sometimes called “Granton edges,” these have shallow divots ground into the side of the blade. These create air pockets to prevent food from sticking to the blade, making them ideal for slicing thin cuts of meats and fish. Some examples include:

  1. Santoku Knives: A popular type of kitchen knife in both professional and home settings, the Santoku often features hollow edges. It’s designed for precise cutting, dicing, and mincing, making it ideal for handling vegetables, fruits, and boneless meats.
  2. Carving Knives: These knives are used to slice thin cuts of meat, such as roast beef, turkey, or ham. The hollow edges allow for clean slices without tearing the meat, as the air pockets prevent the meat from sticking to the blade.
  3. Fish Fillet Knives: In filleting fish, where precision is key, hollow edges help by preventing the delicate fish meat from adhering to the blade, allowing for smoother, cleaner cuts.

Although hollow edges are less about enhancing the cutting ability and more about the precision and ease of slicing, they still benefit from regular maintenance to keep the actual cutting edge sharp.

Knife Edge Anatomy

  • Bevel: This is the angled surface that forms the edge. Most kitchen knives have a double bevel, meaning both sides taper down to form the edge. Some specialty knives might have a single bevel, like many traditional Japanese knives.
  • Angle: The angle of the bevel greatly affects the sharpness and durability of the edge. A steeper angle (like 15 degrees) is sharper but more delicate, while a wider angle (around 20-25 degrees) offers more toughness but less sharpness.
  • Edge Retention: This term describes how long a knife can hold its sharpness during use. Higher-quality steel and specific blade treatments can enhance edge retention.

Knowing your knife’s edge type and anatomy helps you understand how to sharpen and maintain it properly. Each type of edge and angle serves a purpose and requires specific care to keep them in the best condition for cutting.

Signs That Your Blade Needs Sharpening

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

Keeping your knives sharp isn’t just a matter of routine—it’s about recognizing when they start to lose their edge and taking action. If you’re wondering when (and how often) knives need to be sharpened, here are a few indicators:

Performance Test: The most straightforward way to check your knife’s sharpness is by using it. If you find yourself applying more pressure than usual or if the knife is squashing rather than slicing cleanly through food, it’s probably time to sharpen. For chefs, a knife that drags or slips could not only ruin your prep work but also pose a safety hazard.

Visual Inspection: Take a close look at the edge under a strong light. Any nicks, dents, or dull spots are telltale signs that your knife needs some attention. A shiny edge, as opposed to a matte finish on a freshly sharpened blade, usually indicates dullness.

The Paper Test: This is a simple yet effective test. Hold a piece of paper by one end and try slicing it with the knife. A sharp knife should cut through easily with a clean, straight line. If the blade catches or tears the paper, it needs to be sharpened.

Tomato Test: Another practical method is the tomato test. A well-sharpened knife should easily slice through a ripe tomato with minimal pressure. If the knife squashes the tomato or can’t cut the skin cleanly, it’s time for a sharpening.

Once you’ve determined that your knife needs sharpening, the next step is to select the right tool and technique for the job. Each sharpening method has its own benefits and suits different types of knives, which we’ll explore in the next section.

Tools for Knife Sharpening

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

Choosing the right tools is crucial for effective knife sharpening. Each type of sharpener offers different benefits, and understanding these can help you select the best one for your knives. Here’s a breakdown of the most common sharpening tools:

Whetstones (or Sharpening Stones)

  • Description: These are blocks of abrasive material that you use to grind and hone the edge of a knife blade. Whetstones come in various grits—coarse, medium, and fine—which correspond to the degree of sharpness you want to achieve.
  • Use: To sharpen a knife with a whetstone, you need to soak the stone (if it’s a water stone), set it on a stable surface, and then draw the edge of the knife across the stone in smooth, controlled strokes. You’ll do this on both sides of the blade to maintain an even edge.
  • Advantages: Provides great control over the sharpening process and allows for a precise, custom edge.
  • Drawbacks: Requires some skill and practice. The process can be time-consuming.

Electric Sharpeners

  • Description: These devices have built-in abrasive wheels that spin when powered on. You pull the knife through the designated slots to sharpen the blade.
  • Use: Electric sharpeners are user-friendly—just plug in the machine, turn it on, and draw your knife through the slots as directed.
  • Advantages: Quick and easy to use, requiring minimal skill.
  • Drawbacks: Less control over the sharpening process and can remove more material from the blade than necessary, potentially shortening the knife’s lifespan.

Honing Rods

  • Description: Also known as sharpening steels, these rods are made from ceramic or metal and are used to realign the edge of the blade, maintaining its sharpness between more intensive sharpenings.
  • Use: You slide the blade along the rod at the appropriate angle, applying light pressure. This is more about maintenance than actual sharpening.
  • Advantages: Extends the life of your blade’s edge and is quick to use.
  • Drawbacks: Doesn’t actually sharpen dull blades; it just realigns the edge.

Pull-Through Sharpeners

  • Description: These tools have one or more slots fitted with abrasive wheels or ceramic rods that sharpen the knife’s edge as you pull it through.
  • Use: Simple and straightforward—pull the knife through the slot, applying even pressure.
  • Advantages: Easy for beginners to use and very quick.
  • Drawbacks: Offers less control and consistency than manual methods and can be harsh on knives.

Choosing the right sharpening tool depends on the type of knives you have, your skill level, and how much time you’re willing to invest in the process. No single method suits every situation, so it might be beneficial to have a couple of different sharpeners on hand.

Preparation for Sharpening

Before you start sharpening your knives, setting up your workspace properly and ensuring you have all necessary safety measures in place are key steps to a successful sharpening session. Here’s how to prepare:

Setting Up Your Workspace

  1. Choose a Stable Surface: Make sure your sharpening station is on a stable surface. Any slipping or shifting could affect your sharpening precision or even lead to injury.
  2. Use a Non-Slip Mat: Place a non-slip mat or damp towel under your sharpening tools to prevent them from moving.
  3. Good Lighting: Adequate lighting is crucial. You need to see clearly to maintain the angle and pressure required for effective sharpening.
  4. Keep It Clean: Ensure the area is clean and free from distractions. A cluttered workspace can lead to mistakes and accidents.

Safety Equipment

  • Cut-Resistant Gloves: Wearing cut-resistant gloves can provide an extra layer of protection, especially for beginners or when using aggressive tools like electric sharpeners.
  • Safety Goggles: Wearing goggles can protect your eyes from any fine metal filings or stone dust generated during the sharpening process.

Preparing the Knife and Sharpening Tools

  • Clean Your Knife: Start with a clean knife. Any residue on the blade can affect the sharpening process.
  • Choose the Right Sharpening Tool: Based on your knife type and the condition of the blade, select the appropriate sharpener. Remember, different tools are suited for different stages of sharpness and types of knives.
  • Prepare Your Sharpening Tool: If you’re using a whetstone, for instance, some types need to be soaked in water for about 10 to 15 minutes before use. Check the manufacturer’s instructions for specifics.

Sharpening Techniques

Once your workspace is set up and everything is in place, the sharpening process can begin. Here’s an overview of how different sharpening tools can be used:

Using a Whetstone

  • Angle Consistency: Maintain a consistent angle between the knife and the stone—usually around 15-20 degrees. You can use an angle guide if you’re unsure.
  • Smooth Strokes: Draw the blade across the stone in smooth, even strokes, covering the entire length of the blade. Repeat this process, gradually switching from coarser to finer grits to refine the edge.
  • Checking Your Work: Periodically check the sharpness of your knife and the evenness of the edge. Adjust your technique as needed.

Using an Electric Sharpener

  • Start with the Coarsest Slot: Begin with the coarse slot if your knife is very dull, then move to finer slots to hone the edge.
  • Even Pressure: Apply steady, moderate pressure as you pull the knife through the slot. Avoid pushing down too hard, as this can damage the blade.
  • Repeat as Necessary: It might take several passes through each slot to achieve the desired sharpness.

Using a Honing Rod

  • Regular Maintenance: Use the honing rod regularly between thorough sharpenings to keep the edge aligned.
  • The Right Angle: Hold the knife at the correct angle and draw it down and across the rod, from heel to tip, and then switch to the other side of the blade.

Using Pull-Through Sharpeners

  • Simple and Quick: Simply draw the blade through the appropriate slot a few times to sharpen. These tools are straightforward but offer less control over the final edge quality:
    • Potential for Over-Sharpening: Pull-through sharpeners often remove more metal from the blade than necessary, leading to excessive wear and shortening the lifespan of your knife.
    • Limited Edge Options: These sharpeners typically provide a predetermined angle, which may not be suitable for all types of knives. For knives with specialized edge angles, such as Japanese-style knives, pull-through sharpeners may not produce the desired results.
    • Risk of Damaging Blade: Improper use of pull-through sharpeners can result in uneven sharpening, burrs, or even damage to the blade edge. Without proper control over the sharpening process, there’s a higher risk of compromising the structural integrity of the knife.

Each sharpening tool and technique has its place—and mastering them takes more than a little practice.

Special Considerations for Different Types of Knives

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

Sharpening isn’t a one-size-fits-all deal—what works for your hefty butcher knife isn’t going to be ideal for your delicate paring knife. Each knife in your drawer has its own quirks and needs when it comes to keeping it sharp.

Getting to know these differences not only keeps your knives cutting smoothly but also helps you take better care of them over time.

Here’s a breakdown of what to keep in mind for various types of knives:

Kitchen Knives

  • Chef’s Knives and Santokus: These are typically sharpened at an angle of about 15-20 degrees. They benefit greatly from regular honing and should be sharpened on a whetstone for best results.
  • Paring and Utility Knives: Due to their smaller size and varied usage, maintaining a sharp edge is crucial for precise tasks. A fine grit stone can be particularly effective.

Outdoor and Tactical Knives

  • Survival Knives: These are generally made from tougher steel to withstand rough use, including cutting through wood or even prying. They are often sharpened at a sturdier 20-25 degree angle.
  • Pocket Knives: Compact and used for a variety of tasks, these knives need regular maintenance. A portable sharpener or pocket stone can be handy for on-the-go adjustments.

High-End and Delicate Knives

  • Japanese Knives: These can feature thinner blades and sharper angles (often about 10-15 degrees). They require careful handling and should be sharpened primarily on high-quality whetstones.
  • Ceramic Knives: These should not be sharpened at home unless you have a sharpener specifically designed for ceramic blades, as they can easily chip or crack.

Serrated Knives

  • Special Tools Required: Serrated knives do not fit well into standard sharpeners and require a serrated knife sharpener or a honing rod that fits into their grooves.
  • Technique: Sharpen only the serrated side of the knife to preserve the tooth-like structure, which is crucial for its cutting efficiency.

Meat Shears and Scissors

Meat Shears

  • Usage and Care: Designed specifically for cutting through meat and poultry, meat shears must handle tougher materials than typical scissors. Because they encounter everything from skin to bone, maintaining a sharp edge is crucial for clean cuts and ease of use.
  • Sharpening Angle: Meat shears generally benefit from a slightly steeper sharpening angle—about 20-25 degrees—due to their heavy-duty nature.
  • Technique: It’s essential to disassemble the shears, if possible, before sharpening to ensure each blade is handled correctly. Use a whetstone or a dedicated scissor sharpener to maintain precision.


  • General Maintenance: Regular scissors used in kitchens or for crafts also require frequent sharpening, as dull blades can lead to imprecise cuts and increased effort during use.
  • Sharpening Angle: Most scissors are best maintained with an angle of about 20 degrees, which provides a good balance between sharpness and blade strength.
  • Tools and Techniques: A small handheld sharpener can work well for standard scissors. For a more thorough sharpening, using a fine grit whetstone can yield better results. Always ensure that the blades are cleaned and dried thoroughly after sharpening to prevent rust, particularly if they are used in moist environments like kitchens.

Both meat shears and regular scissors benefit significantly from regular care and maintenance. Keeping these tools sharp not only makes cutting tasks easier but also extends the life of the tools, ensuring they are always ready (and efficient) when you need them.

Maintaining Your Knives

Regular maintenance extends the life of your knives and make sure they are always ready when you need them. Here’s how to keep them in tip-top shape:

Regular Honing

  • Honing vs. Sharpening: Understand that honing realigns the edge of the knife without removing much, if any, metal. This should be done regularly, possibly before each use, while actual sharpening, which grinds away metal to create a new edge, is less frequent.
  • Using a Honing Rod: A few strokes on the honing rod before or after each significant use can keep your knife’s edge aligned and sharp.

Proper Storage

  • Knife Blocks or Magnetic Strips: Store your knives in a block or on a magnetic strip to keep the edges protected. Avoid tossing them in a drawer, where they can get banged up or dulled.
  • Sheaths for Outdoor Knives: For camping or tactical uses, keep knives in sheaths to protect the blades and ensure safety when not in use.

Cleaning and Care Tips

Cleaning and caring for your knives properly is essential to ensure they remain sharp, reliable, and ready for use. Here are some best practices:

  1. Hand Washing: Always wash your knives by hand with warm, soapy water immediately after use. Hand washing allows for greater control over the cleaning process and helps prevent the buildup of food particles and residue on the blade. Use a soft sponge or cloth to gently clean the blade, taking care to avoid harsh scrubbing that could damage the knife’s surface.
  2. Drying Immediately: After washing, dry your knives promptly with a clean towel to prevent moisture from lingering on the blade. Moisture can lead to rust or corrosion, especially on knives made from high-carbon steel. Ensure that the knife is thoroughly dried, including any crevices or joints where water may accumulate.
  3. Avoid Dishwashers: Again, while it may be tempting to toss your knives into the dishwasher for convenience, it’s best to avoid this practice. The harsh environment inside a dishwasher—high heat, abrasive detergents, and jostling with other utensils—can damage knife handles and dull the blades quickly. Additionally, the prolonged exposure to moisture can accelerate corrosion, especially on knives with wooden handles.
  4. Storage: Store your knives properly to protect them from damage and maintain their sharpness. Consider using a knife block, magnetic strip, or blade guards to keep the blades safely stored and prevent them from coming into contact with other utensils. Avoid storing knives loose in drawers, as this can lead to nicks and scratches on the blade edges.

Troubleshooting Common Sharpening Mistakes

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

Even with the best intentions, sharpening mistakes can happen, so knowing how to recognize these errors is important.

While this article explores some common sharpening mistakes to help you keep your knives in good shape, achieving an exceptionally sharp and long-lasting edge often requires specialized equipment and expertise. So, for safety, blade performance, and to avoid potential damage to your knives, we highly recommend having your blades sharpened professionally.

That said, here are some common issues:

Uneven Edges

  • Symptom: The knife seems sharper on one side than the other, or the edge looks visually uneven when inspected under light.
  • Solution: This usually occurs from applying uneven pressure or holding the knife at inconsistent angles during sharpening. Practice maintaining a consistent angle and pressure. Use angle guides if needed, and frequently check your progress. For best results, take your knife to a professional sharpener.

Over Sharpening

  • Symptom: The blade becomes too thin, making it brittle and prone to chipping or breaking.
  • Solution: Avoid over sharpening by limiting the number of strokes on each side of the knife and not using excessively coarse grits unless necessary. It’s better to sharpen more frequently with gentler methods than to remove too much material at once.

Scratches on Blade Surface

  • Symptom: Visible scratches perpendicular to the edge, typically from improper use of a honing rod or mishandling on stones.
  • Solution: Ensure that you are using the honing rod or whetstone correctly by keeping the knife’s movement smooth and controlled. For whetstones, use a proper base to keep the stone stable, and consider a finer grit for finishing.

Not Achieving Desired Sharpness

  • Symptom: The knife doesn’t feel sharp enough after several attempts at sharpening.
  • Solution: This could be due to not starting with a coarse enough grit to reshape the edge or not finishing with a fine enough grit to polish it. Assess the starting condition of your knife and choose the appropriate grit sequence. Also, make sure you are flipping the knife regularly to sharpen both sides equally. For best results, take your knife to a professional sharpener.

Failing to Maintain Sharpness

  • Symptom: The knife loses its edge quickly after sharpening.
  • Solution: This could indicate a need for better edge maintenance through regular honing or possibly using a sharpening steel in between more thorough sharpening sessions. Also, consider the type of cutting surfaces you are using—wooden and plastic cutting boards are kinder to knives than glass or metal, which can dull your edge faster.

Tips for Sharpening Serrated Knives

  • Reminder: Serrated knives require a different approach. Use a sharpening rod that fits the serrations or a specially designed serrated knife sharpener. Focus on sharpening the gullet (the curved part of the serration) and not just the tips. Again, for best results, bring your serrated knife to a professional sharpener.

Advanced Tips

  • Stropping: After sharpening, use a leather strop to refine and straighten the edge further. This can increase the sharpness and longevity of the blade’s edge.
  • Micro-Adjustments: Sometimes, minor adjustments in angle or pressure during the sharpening process can make a significant difference in outcome. Be observant and responsive to how the knife feels as you work on it.

Advanced Tips & Techniques

A picture of Don't Be Blunt: A Practical Knife Sharpening Reference with Edison Vacuums

For knife enthusiasts interested in understanding more sophisticated sharpening techniques, there are several advanced methods that can significantly enhance the performance of your knives.

These techniques, often employed by professional sharpeners, are crucial for achieving that meticulously sharp edge typical of high-quality cutlery. While we generally do not recommend anyone attempt advanced knife sharpening at home, here is a broad overview of some advanced sharpening strategies used in professional settings:

Custom Sharpening Angles

Different tasks may require different edge angles. For example, delicate slicing might benefit from a sharper angle (around 15 degrees), while chopping tough materials might need a more robust edge (around 20-25 degrees).

While experimenting with angles can be insightful, professional sharpeners have the tools and expertise to precisely match the angle to the knife’s intended use, ensuring optimal performance.

Using Strops for Edge Refinement

  • Leather Strops: After sharpening, running the blade along a leather strop can help polish the edge and remove any burrs left from the sharpening process. This results in a smoother and sharper finish.
  • Compound Strops: Apply a fine abrasive paste to the leather for an even finer edge. This can significantly enhance the sharpness and longevity of the blade.

DIY Sharpening Tools & “Hacks”

Sandpaper Sharpeners

If you ask the internet, you’ll be told that you can create a makeshift sharpener by attaching various grits of sandpaper to a flat surface, as a cost-effective alternative to buying multiple whetstones. However, there are numerous reasons why this is not ideal or recommended—especially for sharpening important or high-quality blades:

  1. Uniformity: High-quality sharpening stones offer a consistent grain and hardness, which help maintain a uniform sharpening angle and pressure. Sandpaper might not provide the same level of consistency, especially as it wears down unevenly with use.
  2. Precision: It’s often harder to maintain stable and precise control with sandpaper compared to a traditional whetstone or professional sharpening tool. This can lead to uneven edges or unintended changes in the blade’s angle.
  3. Particle Size: While sandpaper comes in various grits, the particle size can be less uniform than in specialized sharpening stones. This might not affect rough sharpening but can be detrimental when fine-tuning an edge, leading to scratches or a less sharp finish.
  4. Wear Rate: Sandpaper wears out quickly. As the abrasive particles wear down or fall off, the sandpaper becomes smoother and less effective. This can result in inconsistent sharpening if not replaced frequently.
  5. Material Removal: Sandpaper might remove more material from the blade more quickly than a whetstone, particularly if not used carefully. This can shorten the lifespan of the blade by thinning it excessively with each sharpening session.
  6. Heat Generation: Rapid material removal can also generate more heat, which, if excessive, may alter the temper of the steel. This weakens the blade, making it more prone to wear and breakage.
  7. Risk of Scratching & Marring: The less uniform texture of sandpaper, especially as it begins to wear, can leave scratches or mar the finish of a high-quality blade, potentially damaging its aesthetic and functional integrity.
  8. Professional Standards: For blades that require the utmost sharpness and edge retention, such as chef’s knives, professional tools, or finely crafted specialty blades, professional sharpening will help make sure that the edge is correctly shaped and honed without compromising the blade’s integrity.

While a sandpaper sharpener can be a makeshift solution for less critical sharpening tasks, it’s definitely not recommended for important blades. For valuable or finely crafted knives, using higher-quality sharpening methods and tools or entrusting them with a professional knife sharpening service will make sure that they are maintained correctly and continue to perform well over time without unnecessary wear or damage.

Angle Guides

Angle guides are essential tools in knife sharpening, particularly for beginners or those who want to ensure precision when maintaining their blades. These guides help to hold the knife at a consistent angle relative to the sharpening stone, which is crucial for achieving an evenly sharp edge along the entire length of the blade. Here’s a more detailed look at how angle guides work and why they are important:

What Are Angle Guides?

Angle guides are typically small, adjustable devices that attach to the spine or the back of a knife blade. They are designed to physically limit the angle at which the blade can meet the sharpening stone, ensuring that the edge is sharpened at the correct angle throughout the process.

Types of Angle Guides

  1. Fixed Angle Guides: These are simple, often wedge-shaped tools set to a specific angle, like 15 or 20 degrees. You rest the guide against the stone, and it keeps the blade tilted at the set angle as you sharpen.
  2. Adjustable Angle Guides: More versatile than fixed guides, adjustable models allow you to select and lock in the desired angle. This is especially useful if you have knives that require different sharpening angles.
  3. Magnetic Angle Guides: These use magnets to hold the knife at the correct angle, offering a hands-free approach that can be easier for some users.

Benefits of Using Angle Guides

  1. Consistency: The key benefit of using an angle guide is its ability to maintain a consistent angle. Consistency is crucial because it makes sure that the edge is sharpened uniformly, which is necessary for optimal sharpness and blade performance.
  2. Ease of Use: For beginners, maintaining the correct angle can be challenging and requires practice. An angle guide simplifies this process, making it easier to achieve good results even with limited experience.
  3. Protects the Blade: Using an angle guide helps prevent mistakes such as over-grinding one area of the blade or altering the blade’s angle, both of which can compromise the knife’s effectiveness and longevity.
  4. Versatility: Adjustable guides in particular are useful across a range of knife types, catering to different blade angles required by different cutting tasks.

How to Use an Angle Guide

  1. Attach the angle guide to the blade, ensuring it is securely fastened and positioned correctly according to the manufacturer’s instructions.
  2. Place your knife with the angle guide attached onto the surface of the sharpening stone. Move the knife back and forth across the stone, maintaining light, consistent pressure. The guide will keep the blade at the correct angle, removing the guesswork.
  3. If using an adjustable angle guide, you may need to experiment with different angles to find what best suits each knife, especially if you notice that the knife isn’t performing as expected after sharpening.

Angle guides are a practical addition to any knife-sharpening toolkit, particularly valuable for those looking to maintain a professional edge at home. They help safeguard your knives against common sharpening errors and ensure that each sharpening session enhances your blade’s performance.

High-End Knives

High-end knives, particularly those with high carbon content, require extra care to prevent rust and corrosion:

  • Always dry these knives immediately after washing and apply a light coat of food-safe mineral oil to the blade periodically.
  • Steer clear of harsh detergents and never leave these knives soaking in water.

Some basic knife care can sometimes be managed at home, but for high-end knives, professional sharpening can be beneficial to maintain their condition and performance.

  1. Expertise in Handling: Professionals have a deep understanding of different blade materials and the appropriate care techniques for each. They know how to handle high carbon blades to avoid any damage during cleaning, sharpening, or storage.
  2. Appropriate Tools and Products: Professionals use the right tools and products that won’t damage the knife’s delicate steel. For instance, they use specific, non-abrasive cleaners and apply the correct type of mineral oil to protect the blade without harming it.
  3. Prevention of Rust and Corrosion: Professional knife caretakers are skilled in preventing rust and corrosion, crucial for high carbon knives which are prone to these issues if not dried immediately and oiled regularly.
  4. Avoidance of Common Mistakes: Professionals will ensure that knives are never exposed to harsh chemicals or left soaking in water, common mistakes that can permanently damage high-end blades.
  5. Longevity and Performance: Regular professional maintenance helps knives not only last longer but also perform at their best, preserving your investment in quality cutlery.

Specialty Sharpening

  • Fish Fillet and Boning Knives: These knives require a very flexible and sharp edge due to their specific use in filleting fish and deboning meat. Regular honing and careful sharpening with a fine grit stone are essential.
  • Cleavers: Due to their heavy-duty nature, cleavers may require a tougher angle and can tolerate a rougher grit for sharpening. Pay attention to the specific use of the cleaver, as some are designed for chopping bone while others are for vegetables.

Heat During Sharpening

  • Avoid Overheating: When using power tools like electric sharpeners, be mindful of the heat generated as it can alter the temper of the steel, weakening the blade. If the blade gets too hot to touch, let it cool before continuing.

These advanced techniques require a bit more finesse and understanding but can significantly improve the effectiveness and efficiency of your knife sharpening. Whether you’re a home cook looking to keep your kitchen knives in top form or an outdoor enthusiast maintaining your gear, these tips will help you achieve the best results.
