Hi everyone. Struggling here to maintain a good edge. I've got a couple of paddle strops. One came ready pasted with what I think is green dovo paste. I've also got a couple of the small blocks....( http://www.gentlemans-shop.com/acata...ste.html#a1419 ) I've put the red paste onto one strop but haven't used the black. Can anyone tell me what grade these pastes are and when I should use them. Trying to avoid honing. Really appreciate any help.
