I haven't yet but I might, but has any one tried honing on the back of a coticule. I am not talking about one that is backed with BBW but with the black slate or whatever it is. I mean if it is slate then we already use slate hones so why not. I am not saying I want to use it as a finisher or anything like that or that I think people should. Just curious if anyone has tried it before. I mean when coti's where backed with BBW nobody thought you could hone with it but some person did obviously or there wouldn't be several sites just selling coticule backer as hones no matter how useless it is. Who know, the black slate is probably useless compared to the coticule but who know maybe it will do something. Me thinks I will try it tomorrow and see what happens.
