I like my mini-grip with D2 blade that I got several years ago from Cabela's, and it's served me pretty well. The axis locks are solid, but admittedly they do have a gap where stuff could get in, though I haven't had an issue with that.
Part of what I like about it is what some of you guys don't, that it's a fairly light knife. It also has a thin blade which makes it a good slicer for most of what I do and the D2 maintains a decent edge, it's also an easy opening knife one handed. It's not a perfect knife, but I like it. I mean, to be honest, I'm still searching for that perfect knife, perfect multi-tool, perfect flashlight, etc, etc, etc. LOL!
