I remember really wanting a TNT to carry to the office circa 2000. Saw one with a hole pattern I liked at a dealer and ordered it. Nice and light which was the goal for my monkey suit days. Unfortunately the lock bar didn't work. You could just close the knife with your hand even engaged. The dealer said it should break in so I wasn't worried. Months later I was going to Blade as was Mr. Mayo so I took it with me. When I got to his table and showed him the knife and said if it needed shop work he could have it and I would leave my address. He just looked at me, took the knife, used his finger to insert between the scales and used his thumb to bend the lock bar into a curve, then handed it back. I opened the knife, engaged the lock bar, and still closed it with my finger with barely any effort. He just shook his head and said 'it will break in'. I told him it hadn't yet over thousands of opens and his bending. He told me he wouldn't take it back as it would 'break in'. So I had a dull knife with a useless lock that was now bent.
Worst maker experience I've ever had. I sold it for a loss later that weekend at the restaurant hang out. Of course, the fool is me. If I would've kept it for all these years I could have doubled or tripled my money even with the obvious flaw of the rounded off lock bar!
