This is a very sharp knife. Materials and construction appear to be excellent. However the thumb hole is too small and awkwardly recessed. I had to loosen pivot screws and oil to allow thumb opening with one hand. Still not as easy and natural as my other spydercos. A flipper would have probably been good on this knife.
Knife came as advertised and in great condition. Factory edge still very sharp. Action was smooth and the thumb hole was easier to manipulate that I thought it would be. Great knife!
