Mine came in the mail yesterday. I'm a traditional slipjoint user thru and thru. However, I've always been interested in flippers but they all seemed too large or too "tactical" for my preference. Casually looking through the "general discussion" page, I noticed this thread and really liked the smaller, more pocket friendly look of this knife. So I figured I'd track one down just to see what I thought of carrying a flipper/pocket clip knife. So far, I think it's pretty cool and could prove to be a pretty handy knife. I'd be lying if I attempted to describe the lock up or detent as I have no idea of what that really is (ok, I have some idea) since I really don't have another knife in my collection to compare it against. So I'll just stick with the description that this is a pretty cool knife!
