3D Printed Knife Sharpener. Upgrade your mug! by benchapman Aug 14, 2012

Description

Print this and attach it to the bottom of a ceramic mug. If your mug is slightly smaller, wrap it with some electrical tape.
It holds a knife at a 20 degree angle so that it gets honed by the ring of unglazed ceramic on the mug.
Have fun with it! Please feel free to add to it and improve.

Clever! I know Jacques Pepin encourages the use of ceramic dish bottoms as a sharpening surface, but I've never been able to get the angle right. This looks like a great fix for that.
This is very very cool, what is the diameter of the mug hole?
