I've adjusted my blade to the center of the liner, but need to adjust the lock engagement, how?

If the liner does not have enough engagement on the back of the blade after you line the blade up to the center of the liner. You can: 1. Take a little of the back of the liner. This can be done in several ways. A file (or dremmel tool with a cut off wheel)... or another type tool of your choice can be used. Be careful to only take a very little amount off the liner at a time before re-testing If you take too much off at one time, the knife will not be repairable. Or, 2. remove a slight amount off of the edge of the blade rear. (This is not the recommended method, as this can lead to lock failure if not performed properly.)
