I bought a VTech Talon Karambit which looks cool as balls, but literally started falling apart right out of the box. I flicked it open several times and the handle screws popped out permanetly.
The factory QC is non-existent. The supposedly G-10 grips were sharp and frayed and all of the frame screw have started popping out. VTech spent more on the box and rubber box insert than they did on the knife. $19 gone forever.
