I've had QC issues with a few QSP knives now, including an early Parrot. The exposed corner of the lock bar on mine was sharp enough to cut flesh. Meanwhile, the factory edge crapped out in a hurry. Yeah, I get that factory edges can be burnt or fatigued from the factory grinding. However, I'd expect it to be good enough to carry right out of the box. I got visible rolls and flattening of the edge after cutting up a few Amazon boxes to fit in the trash.
