Just to throw a wrench in the works, check out the up and coming Kershaw OD-1. It should be out in September. Frame lock, G-10, under 3". It also has a flipper. I'm standing by with money in hand for one.
That being said, I carry a mini-grip every day at work (coast guard). It gets a lot of hard work it wasn't designed to do. It's opened paint cans and beer bottles, cut every line you can imagine, both clean and loged with salt and sand. The thing never complains, just keeps going. Mine has the "spydie" hole, which I got only because the stud version was out, but I'm glad I did. Much easier to open with gloves on.
