I came across a small hone today. The gent that I bought it from said that it came along with some strops. I have no idea what kind of hone it is so I thought I would as you guys. It's dark brown and quite hard. One corner has been chipped off and the shows a lighter brown where the stone is exposed. This stone has a lot of grime (probably oil) on it. Are there any tests I can do to confirm what kind of stone it is. I was thinking of lapping it but I'll wait until my diamond hones arrive before I lap it.
