So I have gotten into restoring razors and got my first razor all nice and ready to have a bevel set on it. I already have a DMT D8EE but I had heard it wasn't good for setting bevels on. I went to order a DMT D8E and accidently ordered a DMT D8F. The company shipped it so fast that their customer service wasn't able to swap it before shipping but are offering to RMA it for me if I choose. My question to you guys is, is the D8F too coarse a stone to set bevel on and I should send it back or is it ok to use?
