KME Hatchet/Axe Sharpener

This uses the ball joint, backplate, nut and stones from your KME for axe sharpening. KME sells a product similar to this but my version is taller so that you can put a micro/secondary bevel.

My axes were shaving sharp in a few minutes of using this.

Is a shorter version of the jig that is tall enough to put a 25-35 degree 2nd bevel on my 2lb hatchet.

Is a 1.5" taller version of the jig (pictured) capable of sharpening larger axe heads. I only had a 6lb axe head to test it with.

8 x 8x3mm magnets help hold down the jig on the axe head. Magnets can have wide tolerances so the slots might be slightly oversized. A dab of super glue or epoxy will hold them in place if too loose. It doesn't take a lot of force to use the KME. You could most likely use this with NO MAGNETS, holding it steady with one hand while you sharpen with the other. 

Limitations:
-I didn't want to make the jigs much taller than they are so you might be limited with very large axe heads. My version was designed to work on an axe with a fairly square butt. It does not rotate sideways so that you can sharpen double bitted axes like the official KME one.
