This is a terrific knife. Virtually fall shut frame lock. There is no jimping whatsoever and it's not needed. It's almost impossible to fail blade deployment with the flipper tab, however, I am unable to open using the hole in the blade (which I don't care about anyway). The ergos are really good for my everyday large hand size. This is the first knife I've bought that I've not had a desire to disassemble, lube and tune - it's perfect the way it is. I'd buy another in a heartbeat if I lost this one, very cool design. This retails for $259 everywhere but WMK. WMK price is $195 less 10% discount code I paid about $175.
