Sharpening a knife is an important task that can be done with a variety of tools. One of the most popular and effective tools for sharpening knives is a leather strop. A leather strop is a piece of leather that is stretched over a wooden or metal frame. The leather is then treated with a sharpening compound, which helps to create a fine edge on the knife. Using a leather strop is a relatively simple process, but there are a few things you need to know in order to get the best results. However, if you do not have the right technique, you can end up damaging the knife.
Before you start using a leather strop, you need to make sure that the strop is properly tensioned. The strop should be tight enough so that it does not sag, but it should not be so tight that it is difficult to move the knife across it. Once the strop is properly tensioned, you can apply a sharpening compound to the leather. The sharpening compound will help to create a fine edge on the knife.
To use a leather strop, hold the knife in one hand and the strop in the other hand. Place the knife on the strop at an angle of about 20 degrees. Draw the knife towards you, using a light, even pressure. As you draw the knife towards you, lift the heel of the knife slightly. This will help to create a burr on the edge of the knife. Once you have created a burr, flip the knife over and repeat the process on the other side. Continue stropping the knife until the burr is gone and the edge is sharp.
Understanding the Anatomy of a Leather Strop
A leather strop is an indispensable tool for maintaining the sharpness and longevity of your knives and razors. It comprises several key components, each playing a specific role in the stropping process.
1. Handle
a) Material:
The handle is typically made of wood or leather, providing a comfortable and secure grip during stropping. Wooden handles are often ergonomic, allowing for prolonged use without strain. Leather handles, on the other hand, provide a more rustic and traditional feel.
b) Shape:
The shape of the handle varies depending on the strop’s design. Some handles are straight, while others have a curved or contoured shape for better handling. The handle’s dimensions should fit comfortably in your hand, allowing for precise and controlled stropping.
c) Length:
The length of the handle is a matter of personal preference. Longer handles offer greater reach, while shorter handles provide better maneuverability. Consider the size of your workspace and the specific knives or razors you will be stropping when choosing a handle length.
2. Suspension System
a) Riveted:
In this design, the leather strop is attached to the handle using rivets. Rivets provide a secure and durable connection, ensuring that the strop remains taut and aligned during use.
b) Sewn:
Some strops are sewn onto the handle using heavy-duty thread. This method allows for more flexibility in the strop’s positioning and can accommodate strops of different sizes and materials.
c) Tied:
In this simplest design, the strop is tied onto the handle using leather or cord. This method is less secure than riveting or sewing, but it is also more adjustable, allowing the strop to be positioned and tensioned to the user’s preference.
3. Leather Panel
a) Material:
The leather panel is the working surface of the strop, responsible for abrading the knife or razor blade. High-quality strops use genuine leather, typically from cow, horse, or buffalo, due to its durability, flexibility, and ability to hold abrasive compounds.
b) Thickness:
The thickness of the leather panel affects the flexibility and durability of the strop. Thinner leather is more flexible, allowing for finer stropping and better edge control. Thicker leather is more durable and can withstand more demanding use.
c) Surface Texture:
The surface texture of the leather panel can range from smooth to rough. Smooth leather is suitable for initial stropping and general maintenance, while rougher leather is used for more aggressive stropping and repairing damaged edges.
4. Compound Holder
Some strops feature a compound holder, which is a small groove or compartment on the leather panel. This holder allows you to apply abrasive compounds, such as polishing paste or honing oil, to the strop’s surface. Compounds enhance the stropping process and produce a finer and more polished edge.
5. Tensioning Mechanism
In order to achieve optimal results, the leather strop must be kept taut and flat during use. Some strops incorporate a tensioning mechanism, such as a buckle or screw, that allows you to adjust the tension of the leather panel. This ensures that the strop provides consistent and effective stropping action.
Choosing the Right Leather Strop for Your Knife
The type of leather strop you choose depends on several factors, including:
Knife Type: Different knives require different strops. A hard strop is suitable for straight razors and chisels, while a soft strop is better for most other knives.
Blade Material: Softer steels, such as carbon steel, require a softer strop, while harder steels, like stainless steel, can handle a harder strop.
Knife Usage: If you frequently sharpen your knife, you will need a strop with a higher grit to maintain the edge. A lower grit strop is suitable for occasional touch-ups.
Leather Type
The type of leather used in a strop affects its performance. The most common types are:
- Cowhide: Durable and has a moderate hardness. Suitable for most knives.
- Horsehide: Smoother and more flexible than cowhide. Good for finish stropping.
- Pigskin: Soft and has a high friction coefficient. Ideal for stropping straight razors.
- Moosehide: Rare and expensive. Provides a very fine polish.
- Goathide: Soft and has a fine texture. Good for stropping fine knives.
- Synthetic Leather: Affordable and durable. Can mimic the properties of natural leather.
Strop Hardness
The hardness of a strop is measured on the Rockwell hardness scale. The higher the number, the harder the strop.
- Soft (10-20 HRC): Suitable for stropping soft steels and for touch-ups.
- Medium (20-30 HRC): Versatile and works well for most knives.
- Hard (30-40 HRC): Suitable for stropping harder steels and for maintaining a sharp edge.
- Very Hard (40+ HRC): Used for specialized applications, such as stropping straight razors or removing burrs.
Strop Grit
The grit of a strop refers to the size of the abrasive particles embedded in the leather. The higher the grit, the finer the polish.
- Coarse (600-1200 grit): Removes burrs and sets a new edge.
- Medium (1200-2000 grit): Refines the edge and improves sharpness.
- Fine (2000-3000 grit): Polishes the edge and produces a mirror finish.
- Ultra-Fine (3000+ grit): Maintains a mirror finish and removes any remaining burrs.
Strop Length and Width
The length and width of a strop depend on the size of your knife and your personal preferences. Generally, a strop that is twice the length of your knife is sufficient. The width should be wide enough to accommodate the entire blade.
Choosing a Commercial Strop
If you prefer not to make your own strop, there are several commercial options available. Look for a strop that meets the following criteria:
- Made from high-quality leather
- The appropriate hardness for your knife
- The desired grit size
- The correct length and width
Conclusion
Choosing the right leather strop for your knife is essential for achieving optimal performance. Consider the factors discussed in this article to make an informed decision. By choosing the appropriate strop, you can keep your knives sharp, well-maintained, and ready to perform any cutting task with precision and ease.
Proper Knife Maintenance: When to Use a Leather Strop
A leather strop is an essential tool for any knife enthusiast. It helps to keep your knives sharp and ready to use. But when should you use a leather strop? Here are a few tips:
- After sharpening your knife. When you sharpen your knife, you’re removing metal from the blade. This can create a burr, which is a small piece of metal that can make your knife less effective. Using a leather strop helps to remove the burr and create a smooth, sharp edge.
- Before each use. If you’re going to be using your knife for any extended period of time, it’s a good idea to strop it before you start. This will help to keep the blade sharp and prevent it from becoming dull.
- As needed. If your knife starts to feel dull, you can strop it to bring back its edge. There’s no need to wait until the knife is completely dull before you strop it. In fact, it’s better to strop it regularly to prevent it from becoming too dull in the first place.
How to Use a Leather Strop
Using a leather strop is easy. Here are the steps:
- Hold the strop in your non-dominant hand and the knife in your dominant hand.
- Apply a small amount of honing compound to the strop.
- Hold the knife at a 15-degree angle to the strop and move it back and forth across the surface.
- Continue stropping until the blade is sharp.
Here are some additional tips for using a leather strop:
- Use a light touch. You don’t need to press hard on the strop. In fact, pressing too hard can damage the blade.
- Move the knife in a smooth, even motion. Don’t jerk the knife back and forth. This can also damage the blade.
- Stop stropping when the blade is sharp. Don’t over-strop the blade, as this can also damage it.
Strop Types and Their Uses
There are two main types of leather strops: flat strops and hanging strops.
Flat strops are made of a single piece of leather that is attached to a flat surface. They are typically used for stropping knives that have a straight edge.
Hanging strops are made of a piece of leather that is suspended from a hook or other support. They are typically used for stropping knives that have a curved edge.
The type of strop you choose will depend on the type of knife you have and the type of edge you want to create.
Here is a table that summarizes the different types of strops and their uses:
Strop Type | Uses |
---|---|
Flat strops | Straight edge knives |
Hanging strops | Curved edge knives |
Stropping in Different Directions: Forward and Backward
Forward Stropping
In forward stropping, the knife is pulled away from the body while sliding along the strop. This direction is suitable for most knives, including those with a single-bevel edge. Forward stropping helps to create a fine edge by removing any burrs or micro-serrations.
To perform forward stropping, hold the knife at a 15-20 degree angle to the strop. Place the heel of the blade on the strop and slide it towards you, maintaining the angle throughout the entire stroke. Repeat this motion 10-15 times on each side of the blade.
Backward Stropping
In backward stropping, the knife is pushed towards the body while sliding along the strop. This direction is typically used for double-bevel knives or for touch-ups after forward stropping. Backward stropping helps to polish the edge and remove any remaining burrs.
To perform backward stropping, hold the knife at a 10-15 degree angle to the strop. Place the heel of the blade on the strop and slide it away from you, maintaining the angle throughout the entire stroke. Repeat this motion 10-15 times on each side of the blade.
Stropping Frequency
The frequency at which you should strop your knife depends on several factors, including the type of knife, the frequency of use, and the desired sharpness. Here is a general guideline:
- Daily use: Strop your knife daily or every other day.
- Occasional use: Strop your knife every few days or weekly.
- Infrequent use: Strop your knife monthly or as needed.
Stropping Compound or Paste
Stropping compounds or pastes can be applied to the strop to enhance the sharpening process. These compounds are typically made of abrasives, such as diamond powder or chromium oxide. When applied to the strop, they help to remove metal faster and create a finer edge.
To use a stropping compound, apply a small amount to the strop and spread it evenly over the surface. Then, strop your knife as usual. Be sure to clean the strop thoroughly after use to remove any residue.
Strop Maintenance
To keep your strop in good condition, it is important to clean and condition it regularly. Here are some tips:
- Wipe the strop down with a damp cloth after each use.
- Clean the strop with a leather cleaner every few weeks to remove any dirt or debris.
- Condition the strop with a leather conditioner every few months to keep it supple.
Strop Storage
When not in use, store the strop in a cool, dry place. Avoid exposing it to direct sunlight or heat, as this can dry out the leather and damage it.
Protecting Your Leather Strop: Proper Storage and Maintenance
Maintaining your leather strop is crucial for longevity and optimal performance. Here are the key aspects to consider:

Common Mistakes to Avoid While Stropping
1. Stropping Too Heavily
Applying excessive pressure while stropping can damage your knife’s edge and reduce its sharpness. Use a light, even touch and let the weight of the blade do the work.
2. Using a Dull Strop
A worn or dirty strop will not effectively sharpen your knife. Clean your strop regularly with a leather cleaner and replace it when it becomes too stiff or glazed.
3. Stropping in the Wrong Direction
Always strop in the same direction as the blade’s edge. Stropping in the opposite direction can dull or damage your knife.
4. Stropping at an Incorrect Angle
The ideal stropping angle is 15-20 degrees. Holding the blade at too high or too low an angle can reduce the effectiveness of the stropping process.
5. Overstropping
Stropping your knife excessively can remove too much metal and weaken the edge. A few passes on each side of the blade is generally sufficient.
6. Using the Wrong Type of Strop
Different knives require different types of strops. Hard leather strops are ideal for rough edges, while finer leather strops are more suitable for finishing and polishing.
7. Neglecting to Clean Your Knife
Stropping is less effective if your knife is dirty or covered in grease. Wipe your knife clean with a soft cloth before stropping to remove any debris.
8. Stropping Without Lubrication
Applying a small amount of honing oil to the strop can help to lubricate the blade and reduce friction. This can improve the stropping process and extend the life of your blade.
9. Using a Strop That is Too Narrow
A narrow strop can cause the blade to dig into the leather and create a rounded edge. Use a strop that is at least as wide as your knife blade.
10. Stropping Too Quickly
Stropping should be done slowly and deliberately. Rushing the process can result in an uneven or dull edge.
11. Not Checking Your Edge
After stropping, it is important to check your edge with a knife sharpener or by slicing through paper. This will help you ensure that your knife is properly sharpened and ready for use.
12. Using a Damaged Strop
A strop with cuts, tears, or other damage can compromise its effectiveness and may even damage your knife. Regularly inspect your strop and replace it if necessary.
13. Stropping with a Blunt Blade
Stropping a knife that is already blunt may not produce the desired results. If your knife is very dull, it may need to be sharpened on a whetstone or other sharpening tool before stropping.
14. Stropping Sharpened Knives Only
Stropping is not just for sharpening a dull knife, it can also maintain the sharpness of already sharpened knives. Regularly stropping your knife can extend its life and keep it performing at its best.
15. Stropping with a Dirty or Oily Strop
Dirt and oil can accumulate on your strop over time, which can reduce its effectiveness. Clean your strop regularly with a leather cleaner and apply honing oil to keep it in top condition.
16. Applying Too Much Pressure
Excessive pressure while stropping can cause the knife edge to bend or become damaged. Apply just enough pressure to maintain contact between the knife and the strop, and let the weight of the knife do the work.
Mastering the Strop-Assisted Choil Technique
21. Refining with a Leather Strop
Once you have honed your blade on a whetstone to a keen edge, you can further refine its sharpness and polish it using a leather strop. Strop preparation involves applying a compound to the leather surface. The compound acts as an abrasive that helps remove any remaining burrs and polishes the blade.
21.1 Choosing the Right Strop and Compound
Opt for a strop made of high-quality leather, such as bridle leather, that is dense and firm. The compound should be fine-gritted, such as green or white compound, to avoid scratching the blade.
21.2 Preparing the Strop
Apply the compound evenly to the strop using a small piece of cloth or felt. The amount of compound required varies depending on the size and condition of the strop. Rub the compound vigorously into the leather until it disappears into the surface.
21.3 Holding the Knife
Grasp the knife firmly by its handle with your dominant hand. Your thumb should rest on the blade spine, providing stability. Use your non-dominant hand to gently hold the strop taut.
21.4 Establishing the Stropping Angle
Position the blade on the strop at a shallow angle, approximately 15-20 degrees. The edge should barely touch the leather surface.
21.5 Stropping Technique
Using a gentle and steady motion, slide the knife towards you in a forward stroke. Apply light pressure and let the blade’s edge glide along the leather. Avoid applying excessive pressure, as this can damage the blade or the strop.
21.6 Reversing Strokes
After completing a forward stroke, reverse the knife’s direction and slide it back in the opposite direction. Continue alternating between forward and reverse strokes, maintaining a consistent shallow angle.
21.7 Number of Strokes
The number of strokes required depends on the desired sharpness and the condition of the blade. As a general rule, 10-20 strokes on each side should suffice for a sharp edge.
21.8 Regular Stropping
Incorporate regular stropping into your knife maintenance routine to maintain its sharpness. Stropping can be done as often as needed to touch up the edge or rectify any minor nicks.
Common Mistakes to Avoid When Stropping
- Using a strop with burrs or damaged surfaces.
- Applying excessive pressure, which can damage the blade or strop.
- Stropping at an excessively steep angle, which can result in uneven wear on the edge.
- Failing to maintain a consistent angle throughout the stropping process.
- Over-stropping, as this can weaken the edge and make it more prone to damage.

Using a Leather Strop in Conjunction with Sharpening Stones
If you’re not in the habit of regularly using a leather strop to maintain the sharpness of your knives, you’re missing out on a simple and effective way to keep your blades at their best. A leather strop can be used in conjunction with sharpening stones to achieve a razor-sharp edge on your knives. Here’s how to do it:
1. Choose the Right Strop
The first step is to choose the right strop. There are many different types of strops available, each with its own unique characteristics. Some strops are made from smooth leather, while others are made from rough leather. Some strops are impregnated with compounds, while others are not. The best strop for you will depend on your individual needs and preferences.
2. Prepare the Strop
Before you start using the strop, you need to prepare it. This involves applying a honing compound to the strop. Honing compounds are available in a variety of grits, from coarse to fine. The grit of the compound you choose will depend on the condition of your knife blade. If your blade is dull, you’ll need to use a coarse compound. If your blade is already sharp, you can use a fine compound.
3. Position the Knife
Once the strop is prepared, you need to position the knife correctly. Hold the knife in your dominant hand and place the blade on the strop at a 15-degree angle. The edge of the blade should be facing away from you.
4. Stroke the Knife
With the knife in position, begin to stroke it back and forth along the length of the strop. As you stroke, apply gentle pressure to the blade. The pressure you apply will vary depending on the condition of the blade. If your blade is dull, you’ll need to apply more pressure. If your blade is already sharp, you can apply less pressure.
5. Alternate Strokes
As you stroke the knife, be sure to alternate the direction of the strokes. For example, you might stroke the knife forward three times and then backward three times. This will help to ensure that the edge of the blade is evenly sharpened.
6. Repeat Strokes
Continue to stroke the knife back and forth along the length of the strop until you’ve achieved the desired sharpness. The number of strokes required will vary depending on the condition of the blade and the grit of the honing compound you’re using.
7. Check the Sharpness
Once you’ve finished stropping the knife, check the sharpness by cutting a piece of paper or cloth. If the knife cuts cleanly, then it’s sharp. If the knife doesn’t cut cleanly, then you need to continue stropping it.
8. Maintenance
A leather strop is a durable tool, but it will need to be maintained over time. The strop should be cleaned and oiled regularly to keep it in good condition. To clean the strop, use a damp cloth to wipe away any dirt or debris. To oil the strop, apply a few drops of leather oil to the surface of the strop and rub it in with a clean cloth.
9. Troubleshooting
If you’re having trouble getting a good edge on your knife, there are a few things you can try. First, make sure that you’re using the right honing compound. If you’re using a coarse compound on a sharp blade, you may not be able to get a good edge. Second, make sure that you’re applying enough pressure to the blade. If you’re not applying enough pressure, you may not be able to remove enough metal from the blade to create a sharp edge. Third, make sure that you’re stropping the knife in the correct direction. If you’re stropping the knife in the wrong direction, you may be dulling the blade instead of sharpening it.
10. Safety Precautions
When using a leather strop, be sure to follow these safety precautions:
- Always wear safety glasses when using a strop.
- Be careful not to cut yourself with the knife.
- Keep the strop away from children.
- Do not use the strop if it is damaged.

Stropping Techniques for Specific Knife Purposes
Basic Stropping Technique for Everyday Knives
For general kitchen knives used in daily meal preparation, a simple stropping technique will suffice. Begin by holding the knife perpendicular to the strop, with the edge facing away from you. Apply light to moderate pressure and draw the blade down the strop in a smooth, even motion. Repeat the process 10-15 times on each side of the blade.
Fine Stropping for Delicate Knives
For delicate knives, such as paring knives or utility knives, use a softer strop and reduce the pressure. Apply only enough force to create a fine, polished edge. Stropping these knives for 5-10 repetitions on each side should suffice.
Stropping for High-Carbon Steel Knives
High-carbon steel knives require more frequent stropping to maintain their sharpness. Use a medium-grit strop and apply moderate pressure. Stropping for 15-20 repetitions on each side will help maintain the edge.
Stropping for Japanese Knives
Japanese knives are typically made from hard steel and have a single-bevel edge. When stropping a Japanese knife, hold the knife at a lower angle than with other knives, around 10-15 degrees. Stroke the knife down the strop in a sweeping motion, applying light to moderate pressure. Repeat for 5-10 repetitions on each side.
Stropping for Double-Edged Knives
Double-edged knives, such as pocket knives or multi-tools, require stropping on both sides of the blade. Hold the knife perpendicular to the strop and strop each side for an equal number of repetitions, maintaining the same pressure throughout.
Stropping for Resetting an Edge
If your knife has a dull or chipped edge, stropping can help reset it. In this case, use a coarse-grit strop and apply heavier pressure. Stropping for 20-30 repetitions on each side should improve the sharpness of the blade.
Stropping for Compound Angles
Compound-angle edges, which consist of a flat primary bevel and a convex secondary bevel, require a slightly different stropping technique. Hold the knife at a lower angle (around 10-15 degrees) on the primary bevel and apply light to moderate pressure. Transition to a steeper angle (around 20-25 degrees) on the secondary bevel and maintain light pressure. Repeat for 5-10 repetitions on each side.
Stropping for Convex Edges
Convex edges, which curve continuously from the spine to the edge, require a specific stropping technique. Hold the knife at a low angle (around 5-10 degrees) and apply light, even pressure. Sweep the knife down the strop in a gentle, rocking motion. Repeat for 10-15 repetitions on each side.
Stropping for Serrated Knives
Serrated knives have teeth instead of a smooth edge. When stropping a serrated knife, hold the knife perpendicular to the strop and apply light pressure. Zigzag the knife down the strop, following the contour of the teeth. Repeat for 10-15 repetitions on each side.

Using a Leather Strop to Remove Burrs and Imperfections
A leather strop is an essential tool for keeping your knives and other cutting tools sharp. It can be used to remove burrs and imperfections from the edge of a blade, and to polish the edge to a fine finish.
49. How to Use a Leather Strop to Remove Burrs and Imperfections
-
Hold the strop in one hand and the knife in the other. The strop should be held taut, with the smooth side facing up. The knife should be held at a 15-20 degree angle to the strop.
-
Draw the knife across the strop in a sweeping motion. The motion should be smooth and even, and the knife should be drawn from the heel to the tip.
-
Apply light pressure to the knife as you draw it across the strop. The pressure should be just enough to remove the burrs and imperfections from the edge of the blade.
-
Repeat the motion until the burrs and imperfections are removed. The number of times you need to draw the knife across the strop will vary depending on the condition of the blade.
-
Once the burrs and imperfections have been removed, you can polish the edge of the blade by drawing it across the strop in a series of short, light strokes.
Tips for Using a Leather Strop
- Use a light touch when drawing the knife across the strop. Too much pressure can damage the edge of the blade.
- Keep the strop clean. A dirty strop can transfer dirt and grit to the edge of the blade.
- Apply a small amount of honing oil to the strop before using it. This will help to lubricate the strop and prevent the blade from sticking.
- Store the strop in a dry place when not in use.
Safety Precautions
- Always wear eye protection when using a leather strop.
- Keep your fingers away from the edge of the blade.
- Be careful not to over-sharpen the knife. An overly sharp knife is dangerous and can easily cut you.

How to Use a Leather Strop
A leather strop is a tool used to sharpen and polish the edge of a knife. It is made of a piece of leather that is stretched over a frame. The leather is treated with a compound that helps to sharpen the knife. To use a leather strop, hold the knife in one hand and the strop in the other hand. Draw the knife back and forth across the strop, using a light pressure. The compound on the strop will help to sharpen and polish the edge of the knife.
There are a few different types of leather strops available. Some strops are made with a single piece of leather, while others are made with multiple layers of leather. The type of leather used will also affect the performance of the strop. Strops made with softer leather will be more gentle on the edge of the knife, while strops made with harder leather will be more aggressive.
When using a leather strop, it is important to use a light touch. Too much pressure can damage the edge of the knife. It is also important to strop the knife in the correct direction. Stropping the knife in the wrong direction can dull the edge.
Leather strops are a great way to keep your knives sharp and polished. With a little practice, you can learn to use a leather strop to achieve a razor-sharp edge.
