Might want to check out the MOD Dieter CQD Mk 1, its big all right and the plunge lock is unique. I can see virtually no way for an inadvertent closing of this folder. Its large and allows for a lot of grip surfaces. Nice knife, but a bit specialized in design. I love mine. It engenders the most confidence yet for a folder. I kinda hate liner locks, not because they are weak, but because I am afraid as a lefty, i might disengage them accidentally while using them hard. Blade is 3.75 inches long. So its not an overly long blade on this knife. But it is big size wise.
