It depends on what do u need it for. For the diamond side, most of them have a groove for sharpening fish hooks. And many of them are slightly raise around that groove. For me, I do not like nail nicks, cut outs or groove on my files, I find those to be more of a hindrance than being useful. The later pst 2 models have files that have no groove. If u can find them, they are more useful imo. All depends on what u need them for.

I have them both ways and have never really been bothered by the groove but I can see how it can be a hindrance Nice point, Sam
