Thread: Slate Hone ?

Has anyone tried to use chalk, like schoolroom chalk as a nagura. I did and it works although it is not fine enough to create a razor worthy edge. I guess in a pinch though, a chalkboard and a piece of chalk could be better than nothing. alx

This thread got me thinking about razor sharpeners and their lust for great finishing stones. If you were sharpening almost any other type of tool, you could get away with being creative using anything from slate to cement blocks. But really the choices for us are mostly limited to historical rocks that have been tried and true or relatively recent discoveries in manufactured abrasives.

Alx, we have not used chalk in schools for some time now, if you like I will send you a whole chalkboard and a big box of nagura chalk from surplus and trade you for one of yours

Hey Kingfish
An appealing idea, but I think the shipping would kill the deal for you. alx
