Very interesting. I have one as well. Also from Srdjan. And honestly your experience doesn't sound like mine. But I have been binge buying hones for the past few months so I haven't used it too much.

I have to try it out again but I think that mine had decent cutting pover. And I wasn't struggling as much as you are to make a slurry. Maybe yours comes from a harder strata?

I have a couple of razors to sharpen today so I'll do one of them on the montenegro and report back.
