    Decent

    Very solid and heavy build quality. Action is insanely hard to activate. Firm I get, but this is near unusable. Arrived pretty dull for a expensive knife. This is the ,IV version and blade play is minimal, better than others by a large margin. Would be daily use if the activation wasn't near impossible. Feels like 50 lbs
