This retractable knife is safely and conveniently built directly into a key tag. Molded from durable plastic, it has a tempered razor-sharp blade with a patented one-hand safety action that locks the blade in two open positions for hundreds of uses on the trail, at home, in the office or shop. In addition, it only weighs 3 grams and includes a "key ring" to convienently attach it to your gear. Each knife is attached to a direction card.
