I came across a barber hone marked "Vinco, American Hone Co." with a picture of a ship stamped on it. One side is green, and the other side is red.
Currently, I use a shapton and pasted strop progression (1-4-8k-.5m-.05m). I was wondering what the approximate grit range of this stone might be and if it has a place in my hone system.

I appreciate any input,

Bob
