Spyderco's Compression Lock is one of the most innovative and reliable locking mechanisms in the knife industry. Developed exclusively by Spyderco, this patented design positions the lock between the spine of the handle and the blade, allowing for ambidextrous one handed closing without placing fingers in the blade's path. The result is a lock that is incredibly strong, smooth to operate, and safer to disengage than traditional liner or frame locks. Favored by everyday carry enthusiasts and hard use professionals alike, Compression Lock knives deliver confidence inspiring lockup with an elegant and intuitive design that sets Spyderco apart from the competition.
