Thread: graphite hone?

Has anyone ever heard of a graphite hone. I picked up a 3 lot of hones on Ebay. I only wanted the confirmed "Tytex Carbo42". But one of the others is very puzzling. It is 4 x 2 x 3/8 inches thick. It is black in color and very soft, and has a slight sheen to it, similar to pencil lead. I can actually write with it on a piece of paper. Any ideas??

I've got one just like that. I would describe it as being like a hard wax. I never considered it having graphite in it. I'm sorry but I know nothing about the origin of either of our hones. No box and no imprint does make for many clues.

Ya, hard wax would be a good description too. Thanks for your reply.

Here's some pics.
