If you are looking at a Carborundum and considering its usability as a razor hone, just look at the box if it has one. Carborundum hones were identified either as "Razor Hone" or "Sharpening Stone." You can likely guess which works for razors.

I'm working on a compendium index for all the Carborundums that I have found. I hope to post it soon. The only impediment is taking all the damn pictures for it. In the mean time, here is a list of all Carbos that I know of that are in fact razor hones.

Another find in the same antique store. I picked up a Carborundum 103 for two bucks. Does anyone have an idea where this fits in the cycle?
