I got a M21-02 for a couple of weeks, then sold it afterwards. The blade geometry, cutting power, and the overall strength of the knife was great, but ultimately the aluminum handles were too smooth, and made the knife slippery wet or dry. Also, the LAWKS/AutoLAWKS is pure hype. It's not a secondary lock, it just (sort of) prevents the liner lock from retracting, and probably all would agree that CRKT doesn't make top-end liner locks. The lock placement is also ridiculous (for me personally), as it puts my fingers right in the path of the blade. The axis lock will take a lot more use or abuse.
(I ultimately got a Spyderco Delica.)
