It was actually Chris' idea originally. The paper is adhesive and is meant to be used for shapenning chiaales and lathe tools, especially with curved edges. For example, cut a piece from the sheet and adhere it to a short section of dowel rod. <br><br>My though is to cut pieced to size to fit inside the Altoids tin. In an emergency, I'd stick one on each side of the tin, turning it into a shapening "stone." I didn't prestick them on because I didn't want the adhesive from the electrical tape wrap to gum up the grit.
