Planer Blade Sharpening Jig for 2 blades at 40 degree bevel / edge. Printed parts are the base and shoe. Requires 5 bolts, washers, and wingnuts. Heads of bolts are seated in the base of the shoe, and run up through the base to washer and wingnut at the top. Light finger tight should do it.

Can sharpen with sandpaper laid on flat surface plate (such as granite or plate glass), a large stone (such as a Norton IM-313), or smaller hone "floated" over the edges (try inverting the jig). Easy does it!
