Received my Corto yesterday. The fit and finish was about the worst I ve ever seen on a quality knife. Closed, the blade was so off center that is almost touched the right scale. Open, the side to side blade play was pronounced. On opening the knife , sometimes the lock bar would engage the tang completely and sometimes it wouldn t. I ve adjusted the screws and loctited the pivot screw to eliminate bladeplay. The knife is now better but it is still not well put together. I like the design, but this knife is not worth what I paid for it. I m surprised that it was sold in this condition, used or not. I may or may not try to contact Kizer customer service but I feel it is useful to report my experience with this transaction. My only other Kizer folder bought online is outstanding. Go figure.
