Introduction
彫刻 刀 (choukoku tou) or carving knife is an essential tool for any woodcarver. It allows you to carve intricate designs and shapes with ease. However, like any other tool, it needs to be sharpened regularly to maintain its edge. In this article, we will discuss the basics of sharpening your carving knife in relaxed Japanese language.
Why Sharpening is Important
Sharpening your carving knife is crucial for several reasons. First, a dull knife will make your carving more difficult and can damage the wood's surface. Second, a sharp knife will reduce the risk of injury as it requires less force to cut through wood. Finally, a sharp knife will last longer as it prevents the blade from becoming damaged due to excessive force.
Choosing the Right Sharpening Stone
There are several types of sharpening stones available, each with their advantages and disadvantages. The most common types are water stones, oil stones, and diamond stones. Water stones are the most popular as they are affordable, easy to use, and provide a sharp edge quickly. Oil stones require oil and take longer to sharpen, but they are more durable. Diamond stones are the most expensive but are the most efficient and last the longest.
Preparing the Sharpening Stone
Before sharpening your knife, you need to prepare the sharpening stone. If you are using a water stone, soak it in water for at least 10 minutes before use. If you are using an oil stone, apply a few drops of oil to the surface. Diamond stones do not require any preparation.
Sharpening the Knife
To sharpen your carving knife, hold it firmly with one hand and place the blade against the sharpening stone at a 20-degree angle. Using light pressure, move the blade back and forth across the stone, starting from the base of the blade and moving towards the tip. Repeat this process on the other side of the blade, ensuring that both sides are sharpened equally.
Checking the Edge
To check if your knife is sharp, hold it up to the light and look at the edge. If there are no visible nicks or dull spots, your knife is sharp. Another way to test the sharpness is to make a small cut on a piece of paper. If the knife cuts through the paper cleanly, it is sharp.
Maintaining the Edge
To maintain the edge of your carving knife, strop it regularly. Stropping involves running the blade across a leather or felt strip with a polishing compound to remove any burrs and polish the edge. You can also use a honing rod to realign the edge between sharpenings.
Conclusion

By choosing the right sharpening stone, preparing it correctly, and using the correct technique, you can maintain a sharp edge on your knife and create intricate designs with ease.
