Sturdy non-functional pile of junk.
I saw one of these knives and just had to have one. should have bought the one with the fixed blade.REtracting this blade is ridiculous.Sure it can be done by working the knob but i cut one piece of drywall and had to loosen it so much to get the blade to move that the knife was ready to pop open. what a joke. Oh and my poor sore thumb from working that big knob!!!
