Thread: Carborundum

Hi guys. I've read past posts on carborundums but still need a little clarification.

I bought two as a set for $20 today. The pictures show them to be in very good shape no chips, etc.

here's the description:



"This is for two old sharpening stones. The larger is 6" x 2" x 1" and is marked Carborundum #108 or 109. The smaller is not marked and measures 4" x 2" x 1/2". Both are in very good condition but I do not have lids for either of the wooden boxes. The smaller one is a finer grade the the larger one."

i've read the 108 can't be used for razors. Does that include bevel setting? If it's 109, same thing?

the other (smaller) doesn't have a number. Can anyone tell me based on dimensions if this is ok to use in any part of the razor honing process from bevel setting to polishing?
