A Japanese marking out knife, also known as a Kebiki or a Kiridashi, is a versatile and essential tool in traditional Japanese woodworking. This knife is primarily used for marking out lines and making precise cuts in wood, but over time, the blade can lose its sharpness. To ensure the accuracy and efficiency of your work, it is important to know how to sharpen your Japanese marking out knife.
Before you begin sharpening, it is crucial to select the right sharpening stones. Japanese water stones, such as the 1000-grit and 6000-grit stones, are highly recommended for sharpening this type of knife. These stones provide the perfect balance between efficiency and smoothness, resulting in a sharp and polished edge.
First, soak the selected sharpening stones in water for about 10-15 minutes. This will help to lubricate the stones and prevent the blade from overheating. Place the 1000-grit stone on a stable surface, such as a sharpening stone holder or a wet towel, with the coarser side facing up.
Hold the Japanese marking out knife firmly and position the beveled edge of the blade against the stone at an angle of approximately 15-20 degrees. Use gentle downward pressure and move the blade in a circular motion, covering the entire length of the blade. Repeat this process several times, ensuring that you maintain a consistent angle and pressure.
Once you are satisfied with the sharpness achieved on the 1000-grit stone, proceed to the 6000-grit stone for honing and polishing. Repeat the same circular motion, but with lighter pressure, and for fewer strokes. This finer stone will remove any burrs and refine the edge, resulting in an incredibly sharp and clean cut.
Finally, rinse the blade with water to remove any residue from the sharpening process. Dry the blade thoroughly and test its sharpness by making a few test cuts on a piece of scrap wood. If the knife glides effortlessly and cleanly through the wood, congratulations, you have successfully sharpened your Japanese marking out knife!
Remember, regular maintenance and sharpening are necessary to keep your Japanese marking out knife in optimal condition. By following these steps and practicing proper sharpening techniques, you can ensure the longevity and performance of this indispensable tool in your woodworking arsenal. Happy woodworking!
Choosing the Right Sharpening Tools
To sharpen a Japanese marking out knife effectively, it is important to select the right sharpening tools. The right tools will not only make the sharpening process easier but will also ensure a sharp edge that lasts longer. Here are some factors to consider when choosing sharpening tools:
| Sharpening Stone | Diamond Plate | Honing Guide |
|---|---|---|

A sharpening stone is a traditional tool that is commonly used for sharpening Japanese knives. It is available in various grit levels, which determine the coarseness or fineness of the stone. Coarse-grit stones are ideal for initial sharpening, while finer-grit stones are used for honing and refining the edge. |
A diamond plate is an alternative to sharpening stones. It consists of a metal plate embedded with diamond particles, which are extremely hard and durable. Diamond plates are known for their ability to quickly remove material and create a sharp edge. They are suitable for both initial sharpening and regular maintenance. |
A honing guide is a device that helps maintain a consistent angle while sharpening. It attaches to the blade and acts as a guide for the sharpening tool, ensuring that the blade is sharpened evenly on both sides. A honing guide is especially useful for beginners or individuals who want precise control over the sharpening angle. |
When choosing sharpening tools, it is important to consider the type of knife and the level of sharpening required. Different knives may require specific grit levels or sharpening techniques. Additionally, personal preferences and experience can also influence the choice of sharpening tools. Experimenting with different tools and techniques can help determine the most effective combination for sharpening a Japanese marking out knife.
Sharpening Techniques
Sharpening a Japanese marking out knife requires skill and precision. Here are some techniques to help you achieve a sharp and effective blade:
1. Choose the right sharpening stone: Select a fine-grit stone specifically designed for sharpening Japanese knives. It is important to use a stone that is suitable for the type of steel used in your knife.
2. Prepare the stone: Soak the sharpening stone in water for about 10 minutes before using it. This will help to prevent the blade from overheating during the sharpening process.
3. Find the correct angle: Hold the knife at a consistent angle while sharpening. The angle will depend on the type of knife and personal preference. Start with a 15-20 degree angle and adjust as needed.
4. Sharpen one side at a time: Place the knife on the sharpening stone with the bevel side facing up. Using light pressure, move the blade in a circular motion across the stone. Repeat this process several times until you feel a burr on the bevel side.
5. Switch sides: Flip the knife over and repeat the process on the other side. This will ensure an even sharpening on both sides of the blade.
6. Remove the burr: Once both sides are sharpened, use a leather strop or a fine-grit stone to remove the burr. Gently stroke the blade along the stropping surface or stone to eliminate any rough edges.
7. Test the sharpness: Carefully run your finger along the edge of the blade to check for sharpness. If it feels smooth and cuts through paper easily, then your knife is properly sharpened.
Remember, practice makes perfect when it comes to sharpening a Japanese marking out knife. Take your time, stay focused, and follow these techniques to achieve a razor-sharp blade.
