Material of Razor Edge Hones

[Thomas J Ekman]

What material are the Razor Edge Systems hones made of? I asked them, but they wouldn't tell me directly.
If anyone knows the grit sizes of them, I'd be happy to know that too.

I would like to know also.
I have done some research to try and find out, but its like a million dollar secret or something

Anyone really know.
