The Mantis Cyclops is an innovative and stylish folding neck knife. This Cyclops has a silver anodized 6061 aluminum frame which also acts as a sheath system for the hawkbill style blade. The Cyclops can be worn around the neck and quickly released by simply pulling on the ring (the blade is locked open via an internal liner lock). With a bit of practice the ring can be quickly reattached to the neck chain.
