So I bought a collection of barber supplies because it contained a couple of vintage natural combo coticules. They're about 5" long by a bit less than 2.5" wide and are quite thick (quarter for scale, paper for white balance). I wonder if anyone can tell me more about them, what vein they might be from, etc.
This one has these little red lines that seem to be some sort of mineral?
Whereas this one seems like it might be a bit cracked or something and someone used something black to seal it? On the closeup it looks obvious but I cannot catch my fingernail on this for trying, the cracks are imperceptible to touch. So perhaps these cracks don't diminish the utility of the stone as a hone?
And then there is this super tiny hone like thing. It doesn't feel quite as fine as the coticules though not as coarse as it looks. But if it's not a finishing hone... why is it so very small? Maybe it's something to touch up scissors?
