I've had mine for a week with constant carry and use. It becomes smoother by the day and now the blade just flies out. I'm still not crazy about the clip but the rest of the knife just amazes me. After an initial touch-up with my ultra-fine stones the edge is still hair popping sharp after a week's work of use for opening a few boxes, cuting up food, and general use. I am going to pick up a back-up!
