First Ausus, black satin, is a great knife with one issue.... getting the centering spot on, I just can't get it there. Second Ausus, black black, has no issues with the centering but does have issues with the detent. It's lighter than I would like and a couple heavy shakes will get it to unfold. Doesn't look like the detent ball sits in the hole enough. The dlc on the blade is also not perfect with several imperfections, but they're not bad enough to ruin the knife for me. I'd still recommend this as one of the greatest knives under $50.
