Simple Knife Sharpening Assist Tool

This was a quick drawing that should house an M3 nut and bolt. The idea is that you tighten the jig onto your knife, providing the blade has a reasonable size flat near the backbone as mine does, and it will guide strokes against a stone at a constant 20 degree angle.

I will be printing this in the next couple of days. I will either post pics because it worked or I will delete this thing because it sucks... We shall see...
