I've had one for a few weeks, opens very fast, has angled thumb studs which is nice, puts a better grip on the thumb,lock up is perfect, blade stays centered in handle. comes very sharp from the factory. the inserts are rough, gives a good grip, hangs up in the pocket a bit, but they are still nice. very nicely made overall, the blade is beadblast grey, i would rather have it satin finished, but it cleans up easily. havent done too much cutting with it, maybe someone else has some heavier cutting experience with it.
