This is the best tactical folding knife I've ever owned. I've had absolutely no problems with it after years of use. It always sharpens to razor-sharp and the locking mechanism is second to none. I get ZERO play in the blade or handle when locked open - even after years of use and no adjustments. As far as I can tell, it's just as strong as any fixed blade. This is one of Cold Steel's finest tactical folders and will last me the rest of my life.
