The length of the bevel on a skew chisel should be 1 to 1-1/2 times the thickness of the blade. Generally speaking, a shorter bevel angle makes the tool easier to control. To make sharpening easier, mark a portion of the bevel with a marker before you begin. To set the support tool platform at the correct angle for sharpening, place the tool on the support, adjust as needed until the wheel contacts the entire tool bevel and secure the platform. Slowly rotate the wheel by hand, then inspect the bevel to see if contact is being made across the entire tool bevel. Adjust and repeat as needed, until the wheel removes the marker all the way across the bevel. Now you’re ready to sharpen. Our favorite skew chisel grind utilizes a slight radius along the cutting edge. The radius cutting edge offers better control and is less likely to catch. To sharpen, use your thumb as a fulcrum point to hold the tool in place, while your other hand gently swings the handle side-to-side. Flip the skew chisel over and repeat. When the burr forms on the cutting edge, the tool is sharp and ready for use. When you’re done, the cutting edge should be centered on the blade and the cutting edge should look like this. To create a traditional straight edge grind on a skew chisel, carefully shift the tool side-to-side on the support platform making sure to maintain the same position throughout the process. Now flip the skew chisel over and repeat. When a burr forms on the cutting edge, the tool is sharp and ready for use. When you’re done, the cutting edge should be centered on the blade and the cutting edge should look like this.
