As you can see in the drawing at left, the jig consists of a block with a fence and a stop to position the tool. Acrylic attached to the bottom of the block allows it to glide over a base that holds a strip of sandpaper for sharpening. Since the jig is built to fit a specific chisel, plane iron, or turning tool, you may need to adjust the size or angle to your needs. I chose MDF to make the base. It’s smooth and fl at, so it makes the perfect base for sharpening. The mitered block is made from hardwood.
To finish off the block, I added two glides on each end of the block. The glides are made from acrylic and are glued in place. When the jig is complete, you can clamp it to a worksurface to start sharpening. I cut several extra bases so I can use different grit sandpaper for a progressively finer hone on the blade.
