#046 made it here and I've have been carrying it for a few days. Love it's light weight, good steel, and micarta scales. Don't like it's lock rock. Took it apart yesterday and think the problem might be that the spring is to short. It needs a slightly longer spring to prevent the lock bar from rocking back and up, or a shorter slot cut in the tail piece that it sets into would accomplish the same thing. I tried bending the spring to make it a stronger spring, but this only made the action of the blade more difficult to open and close so I bent it back to normal. These Spitfires have so much going for them for Buck to not get the lock up right.
