Special tweezers for the professional locksmith. Groove on working end of tweezers is designed to hold lock pins or springs for keying lock cylinders. The groove in the tip of the pin tumbler tweezer provides a firm, non-twisting grip on cylinder pins for easy loading. The tip is also milled back so that the outside diameter of a standard .115″ pin extends past the tip. This permits the pin to butt up against the end of the plug follower when loading the upper chambers from inside the lock housing. Length: 6 inches.
