John Kubasek is already known to many as the designer of the successful Credit Card Knife. John Kubasek has now taken the Backup Knife topic one step further and presents the 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 blade 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.
