Description:
This is an unusual desgin for a locking mechanism for a leather slitter. Rather than the traditional screw in the end of the arm, this one uses a spring loaded trigger that registers in nothches in the back of the arm. An additional benefit, according to the inventor, is that pulling the trigger in use will lock the arm tighter.
