Sharpening Process

Sharpening chisels on a stone is a time-honored tradition that produces incredibly sharp edges capable of cutting through even the toughest woods. The process involves using a sharpening stone to remove any burrs or nicks from the blade’s edge while forming a keen edge that can cut cleanly through wood fibers. To start, secure the chisel in a vice, then lubricate the stone with water or oil.

Begin by gently rubbing the bevel against the stone’s coarsest grit, holding it at an angle of roughly 25 degrees to the stone. Use circular or figure-eight motions to cover the entire bevel’s surface, checking frequently to ensure that the bevel is still flat across the whole length of the blade. Once you have a good edge established, switch to successively finer-grit stones until you reach a mirror-like finish.

Finally, hone the edge with a leather strop or buffing wheel to remove any remaining burrs or nicks. With a little practice, you’ll be able to sharpen your chisels like a pro, producing razor-sharp edges that will make your woodworking much more enjoyable and precise.
