How to sharpen a scorpChris Schwarz demonstrates two ways to sharpen a weird tool.
A scorp is a great tool for roughing out bowls, spoons, chair seats, and other concave shapes. It’s similar to a travisher in that way, but it is for rougher work and its curve is compound, not simple.
Inside and outside the curves
For inside curves, Schwarz uses abrasives adhered to a dowel. On the outside of the curve, a flat stick with an abrasive adhered to it does the trick. Always hold the handle of the tool like the neck of a violin and move the abrasive like the bow. Don’t let your hand get in front of or near the cutting edge.
A table saw alternative
A metal plate designed to convert a table saw to a disc sander can be used to sharpen odd-shaped tools. One face has 200-grit sandpaper for grinding. The other face has MDF paper for polishing. Tilt the plate to match the tool’s bevel. Charge the MDF with polishing compound. Turn on the saw and gently touch the blade to the spinning wheel.
