My Typhoon handle is too hard to close and lock, or when in the closed position, the blade edge is close to the edge of the pocket. How do I fix this?

Carefully remove (sand) where the pins touch the handles to adjust the lock tightness, or in the closed position, to adjust the blade so that it's sits lower in the pocket when closed. Be careful, when the blade is not adjusted correctly in the closed position, the edge can be felt with your finger tip when pressing down hard.
