24 gram light-weight Dog Tag Knife. Like its namesake, it is carried around the neck on a ball chain and boasts a thickness of less than 4 mm when retracted (measured without blade pivot point). The chisel grind (single-sided blade grind) provides maximum carrying and operating safety by contacting the titanium liner as closely as possible with the flat backside of the edge. A clever magnetic mechanism also secures the neck knife in the retracted and deployed state; in each case, the action is strictly accomplished with magnetic force, but with a true locking mechanism instead. As a result, accidental deployment is eliminated even when engaged in active/dynamic activities. The back side of the titanium liner is ideally suited for laser engraving of the name, nickname, medical data, etc. Shipped with ball chain and carabiner.
