Thought it would be cool if I could have a small sharpener to touch up so made a ceramic keychain sharpener from a landsky stone
-Cut the plastic off with a hack saw and snapped the ceramic stone with a hammer -straightened it as best I could with a diamond stone -Tried to drill through but that never worked out so took a piece of an old hack saw blade and dulled it with a diamond stone -Bent it with a screw driver, and used epoxy to join it to a split ring to make the keychain tool
