These knives are okay, but I've been down on CRKT lately for a number of reasons.
The Good:
* Knife opens very quickly with flipper feature
* Securely locks with Auto LAWKS
* Blade made of AUS8, which sharpens easily, good edge retention
* Full hilt makes knife secure to hold
The Bad:
* Blade ground on left side, making some cutting jobs difficult for right-handers
* Knife a bit on the small side
* Serrations tend to be a bit rough (bumpy)
All in all, I would go with the CRKT M21-02 or the M21-04 (below, right), with my preference being the latter.
