How to Strop a Leather Skiving Knife: A Step-by-Step Guid

A sharp skiving knife is one of the most useful tools in a leatherworker's workshop. Whether you're thinning leather for wallets, reducing bulk around bag seams or preparing leather for folded edges, a well-maintained cutting edge can make skiving easier and more precise.

Learning how to strop a skiving knife is an important leathercraft skill. Regular stropping helps refine an already sharp blade, keeping it in good working condition between sharpening sessions.

In this guide, we'll explain what stropping does, how to prepare a leather strop and how to maintain your skiving knife using a suitable stropping compound.

What Is Stropping?

Stropping is the process of refining a cutting edge using a strop, commonly made from leather.

A fine abrasive compound can be applied to the strop to assist with polishing the cutting bevel and removing small burrs left behind during sharpening.

Unlike sharpening with coarse abrasives, stropping is generally a fine finishing and maintenance process.

For leatherworkers, stropping can help maintain:

• Skiving knives

• Leather cutting knives

• Head knives and round knives

• Other suitable cutting tools

The technique should always be adapted to the blade's shape and bevel geometry.

Why Is a Sharp Skiving Knife Important?

Skiving reduces the thickness of leather in selected areas. It is particularly useful when making:

• Wallet pockets and cardholders

• Folded leather belt ends

• Handbag gussets

• Leather straps

• Watch straps

• Small leather accessories

• Saddlery components

A sharp skiving knife can help produce smoother, more consistent reductions in leather thickness.

When the cutting edge becomes dull, the knife may drag, tear fibres or require excessive force.

Maintaining the blade can make skiving more controlled and help prevent damage to your work.

What Do You Need to Strop a Skiving Knife?

You'll need:

• A suitable leather strop

• A compatible stropping compound

• A clean skiving knife

• A stable work surface

• A cloth for removing abrasive residue

A leather strop is often made from vegetable-tanned leather attached to a rigid wooden backing.

For suitable applications, consider Bolpol Smurf Poo Stropping Paste, following the manufacturer's instructions.

How to Strop a Skiving Knife

Step 1: Check the blade

Before stropping, inspect the cutting edge.

If the blade has visible chips, significant damage or has become very blunt, it may need sharpening before stropping.

Step 2: Prepare your leather strop

Place the strop on a firm, flat surface.

Make sure the leather is clean and free from dirt or loose particles.

Step 3: Apply stropping compound

Apply a small amount of compatible stropping paste to the leather surface.

You generally don't need to overload the strop with compound. Follow the product instructions for the correct quantity and application method.

Step 4: Identify the bevel

Skiving knives can have different cutting geometries.

Some have a single bevel, while others use a double bevel.

Before stropping, identify the existing bevel and preserve the manufacturer's intended geometry.

Step 5: Strop the cutting edge

Position the blade so its bevel is supported at the correct angle.

Draw the blade across the strop with the cutting edge trailing, rather than pushing the edge into the leather.

Use light, controlled pressure.

Step 6: Repeat carefully

Make several controlled passes, checking the edge as you work.

For single-bevel knives, treat the flat side appropriately without creating an unintended second bevel.

Avoid lifting the blade excessively at the end of each stroke, which can round the cutting edge.

Step 7: Clean and inspect

Remove abrasive residue from the blade.

Check the edge and test cutting performance on a suitable piece of scrap leather.

How Often Should You Strop a Skiving Knife?

There is no universal schedule. The frequency depends on the blade steel, the leather being worked, the amount of cutting and the condition of the edge.

Many leatherworkers find that light, occasional stropping helps maintain cutting performance between sharpening sessions. However, stropping too aggressively or using an incorrect angle can reduce performance rather than improve it.

Stropping vs Sharpening a Skiving Knife

Sharpening and stropping perform different tasks.

Sharpening restores or reshapes a cutting edge using suitable abrasives.

Stropping refines an existing edge and may remove very small burrs.

If your skiving knife is significantly blunt, sharpening is usually necessary before stropping.

Common Skiving Knife Stropping Mistakes

Using too much pressure

Excessive pressure can round the cutting edge.

Changing the bevel angle

Maintaining the correct angle is essential for preserving the blade's geometry.

Using a dirty strop

Contamination can scratch or damage the cutting edge.

Trying to repair a damaged blade by stropping

Stropping is not a substitute for sharpening or repairing a damaged cutting edge.

Leaving abrasive residue on the blade

Always clean the blade before returning to leatherwork, especially when working with pale or natural leather.

Frequently Asked Questions

Can you strop a skiving knife on leather?

Yes. A suitable leather strop can be used to refine the cutting edge of a skiving knife, provided the correct technique is used.

What is the best compound for stropping a skiving knife?

A fine abrasive stropping compound compatible with the blade steel and strop is generally appropriate. Always check the manufacturer's guidance.

Can stropping make a blunt skiving knife sharp again?

Stropping can improve a slightly dulled edge, but a significantly blunt or damaged blade normally needs sharpening first.

Should you strop both sides of a skiving knife?

That depends on the blade geometry. Single-bevel and double-bevel knives require different techniques.
