When National Geographic filmmaker Bryan Harvey brought us the prototype of this new multitool he discovered, we knew he had found something innovative! Hidden inside this Kershaw-manufactured Carabiner are a locking stainless steel knife with partial serration and a unique one-hand opening system, flat and Phillips-head screwdrivers, and a bottle opener. A spring-loaded locking latch keeps it securely attached to your belt or gear until needed, and anodized aircraft- aluminum construction provides years of nearly weightless utility.
