I had a M21 and really liked the handle and wish the CRK&T had not discontinued it. It is a beefier knife than the Vex, at least it looks to be as I've not handled a Vex, and it stood up to some abuse I put it through. I had this knife during a time that I slammed open my blades and I mean SLAMMED. this took a bit of a toll on the poor ole knife but not enough to cause any bladeplay.I have since become a fan of the tight pivot and the gentle opening. I have retired my M21 but once in a while I do get it out to fondle it. I don't know if Kit Carson ever made this exact model, but if he did I would have loved to own one!
That all said, I think the framelock on the Vex would probably be a winning point for it. I really like the lines of this knife and would like to get one at some time, hopefully before they are discontinued.
