I really like the UF cziv. I used it on two straight razors the last weeks and like the results. For my knives it's now my goto stone. Either that, the XXF dmt or the UF sharpmaker rod. I bought this one because I really liked the UF rods and also because I wanted it for my str8's.
After using it for some time, I notice the high polish I can achieve with this in a very short time. I have even used it to get rid of a piece of factory grind on the bm 710 in M390. I could go to a polish with the stone on the benchmade. It's a recurve though, but I found I could finish the knife on the edge of the stone, much like you would on the UF rods. I used some pressure to do this.
Mostly I would go with light pressure too, but don't be afraid to use a shallow angle and some more pressure. Since there is a tendency to increase your sharpening angle the finer the grit (the edge V-plane gets 'rounder' after several grit progression because you're getting rid of the previous' stone grit pattern. therefore, you have to vary the angle a bit more to get to the extrem shoulder to get rid of those scratches and you have to go to the edge, therefore, you 'roll' a bit), I find that polishing with the uf and a sharper angle actually helps keep my edges acute.
It's a nice, large stone.
