How to Sharpen Chisels with a Whetstone
Sharpening chisels with a whetstone is an essential skill every woodworker should master. Chisels, like any other cutting tool, tend to dull over time and lose their sharpness. Fortunately, a whetstone, also known as a sharpening stone, can restore the sharpness of your chisels and keep them in good working condition. Here is a step-by-step guide on how to sharpen chisels with a whetstone:
Step 1: Prepare the Whetstone
Before you begin sharpening, it is important to ensure that your whetstone is clean and moistened. A clean whetstone will provide a better sharpening surface, while moisture helps to keep the chisel cool and prevent overheating. Soak the whetstone in water for about 10 minutes before you start sharpening.
Step 2: Position the Chisel
Place the chisel securely on the whetstone with the cutting edge facing up. Hold the chisel firmly with one hand while maintaining a comfortable grip.
Step 3: Establish the Bevel Angle
Before you start sharpening, it is important to determine the bevel angle of your chisel. The bevel angle is the angle at which the cutting edge is ground. Most chisels have a bevel angle of around 25 to 30 degrees. You can use a protractor or a honing guide to help you establish the correct bevel angle.
Step 4: Begin Sharpening
With the bevel angle established, begin sharpening by moving the chisel back and forth across the surface of the whetstone in a smooth and controlled motion. Ensure that the entire bevel makes contact with the whetstone. Apply moderate pressure and maintain a consistent angle throughout the sharpening process.
Step 5: Check for Burrs
After several passes on each side of the chisel, check for the formation of burrs. A burr is a thin, wire-like edge that forms on the opposite side of the bevel. To test for burrs, gently run your finger across the cutting edge. If you feel a slight ridge, it indicates the formation of burrs.
Step 6: Remove Burrs
To remove burrs, lightly strop the chisel on the whetstone, making several passes on each side. Stropping helps to remove any burrs and refine the cutting edge, resulting in a smoother and sharper chisel.
Step 7: Test the Sharpness
Finally, test the sharpness of the chisel by making a few test cuts on a piece of scrap wood. If the chisel cuts cleanly and effortlessly, it indicates that you have successfully sharpened the chisel with the whetstone.
