I have bought 8 different folders since I bought my Spyderco Endura 4 Wave but none of them have taken its place in my pocket yet. The E4 Wave doesn't cost a lot, has a proven lock, has plastic scales that are easy on the other items in my pocket (and the pocket itself), full metal liners, has TWO great opening systems, and has Spyderco's excellent VG-10 steel. I just can't bring myself to carry anything else.
