I've had a BM Griptillian 551 for a few months now and love the Axis lock. The handle shape, though, I've grown less fond of. The first good knife I ever bought was a CRKT M21-14 which is also the same design as CRKT's M16 series. I love the way the handle feels on the M21, the way its belly is curved in the middle (is there a name for this design?) as opposed to the Griptillian's curve-upwards then sloping down to the back design. I'd like to find a knife with the style of the M21 handle but with an Axis lock. Anyone got any recommendations?
