If you have a chisel ground knife and it’s starting to lose its sharpness, don’t worry! With a few simple steps, you can have it cutting like new again. Sharpening a chisel ground knife is not as difficult as it may seem, and with the right tools and techniques, you can easily restore its razor-sharp edge.
The first step in sharpening a chisel ground knife is to gather the necessary tools. You will need a sharpening stone or whetstone, a honing guide, a lubricant such as water or honing oil, and a leather strop. These tools will help you achieve the best results and ensure that your chisel ground knife is properly sharpened.
Next, you will want to secure your chisel ground knife in a honing guide. This will help you maintain the correct angle while sharpening and prevent any accidental slips. The angle you choose will depend on the manufacturer’s recommendations for your specific knife, but a common angle for chisel ground knives is around 25 degrees.
Once your knife is secure, you can begin sharpening. Start by wetting your sharpening stone or whetstone with water or honing oil, depending on the type you are using.

Continue sharpening until you have achieved a sharp edge on one side of the chisel ground knife. Then, repeat the process on the other side, making sure to maintain the same angle and pressure. After you have sharpened both sides, it’s time to move on to the leather strop.
Using the leather strop, gently run the chisel ground knife along the surface, again maintaining the correct angle. The stropping action helps to polish the edge and remove any remaining burrs. After stropping, your chisel ground knife should be sharp and ready for use.
With these simple steps, you can easily sharpen a chisel ground knife and restore its cutting ability. Remember to take your time and be patient, as sharpening takes practice. Regular maintenance and sharpening will ensure that your chisel ground knife remains in top condition for years to come.
What is a chisel ground knife?
A chisel ground knife is a type of knife blade that has a bevel on only one side, similar to a chisel. This asymmetrical blade design is different from the more common V-shaped grind found on many knives.
The chisel ground blade is typically flat on one side and beveled on the other, with the bevel forming the cutting edge. This design allows for a thinner and more precise edge, making it ideal for tasks that require accuracy and control, such as woodworking and carving.
Chisel ground knives are often used in traditional Japanese woodworking and culinary traditions. The flat side of the blade can be placed flush against a surface, allowing for precise cuts and clean lines. The bevel on the opposite side creates a sharp cutting edge that can easily slice through materials.
It’s important to note that chisel ground knives require a different technique for sharpening compared to knives with a V-shaped grind. The bevel of a chisel ground knife should be sharpened at a specific angle to maintain its asymmetrical shape and cutting performance.
| Pros of a chisel ground knife | Cons of a chisel ground knife |
|---|---|
| Thin and precise cutting edge | Requires specific sharpening technique |
| Ideal for accuracy and control | May be less versatile for certain tasks |
