That's a nice review thread. I'm sure individual knives of the same model vary over a wide range. The grinds on my blade are right on, and the lock has always seated dead center and I've not been able to get it to move along the tang. I would encourage folks to send knives back to the seller or to Spyderco if they arrive with ANY obvious problems, even if you plan to beat the hell out of the knife yourself. When I got my first Persian it had some scratches on the blade that looked like someone had slipped a bit on the grinder. You didn't really notice them unless the light was just right. Anyway, it bugged me, so I sent the seller (flamesnknives on ebay) an e-mail, just generally expressing dissapointment, and he immediately sent me a new knife that he hand-picked, as well as a check to cover the shipping to send the first one back. Class act all the way. It was hard to part with a new toy, especially one that I liked so much. But I'm glad I did it.
