Abstract: An interchangeable backspacer assembly for knives that allows different back spacers to be readily interchanged to selectively incorporate additional functionality, such as lanyard loops, glass breakers, and pry tools, into the knives. The interchangeable backspacer assembly includes a pair of standoffs, a backspacer and a locking set screw. The standoffs are connected between the side members of the knife handle to form an opening for receiving the backspacers at the distal end of the handle. The backspacers are held in place by a locking set screw turned into a threaded bore in the backspacer.

Abstract: The folding knife includes a removable thumb stud slidably mounted on the blade to be selectively positioned along the length of the blade's spine. The thumb stud includes a flat button head and a pair of spaced legs that terminate with an in-turned foot. The blade has a channel cut into the flats on both sides of the blade, which act as tracks for the thumb stud. The opposed feet shiftably seat within the channels and allow the thumb stud to be selectively positioned along the length of the blade spine.
