The knife seems to be well-fitted as far as I can tell. I haven't taken it apart, but from what I can see there aren't any signs of unusual wear. It could be there's a rough spot or something that's not visible causing spring wear on the inside. I'd have thought they'd catch anything like that the first time through, though. I'll ask them to investigate that angle. If the springs fail again, I'm going to request a replacement knife instead of a repair.
