I recieved my random task form PVKT about 3 weeks ago. I really like the blade, it hasnt gotten dull yet, I think it is the nicest and least scary looking knives I own, but I just dont trust it to open all the time. When I first got it it opened super fast, but had so much play in the blade, I could just twist it and pry the liners apart, I tightened the pivot screw, where I thought it was moderately tight, and the thing almost refused to open at all. So I loosened it enough to let it open fully all the time, THere was a ton of blade play still, eventually after lots of lubing, and working the action on it, it is satisfactory to me, but I just don't really trust the lock for some reason. My other complaint is I have one of the old models, and the thumb stud is so rough!!! I have never had any problems with any other knife, but after the first 30 openings, my thumb was sore, and after 50 I had a big hole in my thumb, and was bleeding. Also the thumb stud tends to catch on my pants, when I pull the knife out.
