This is the CRKT Lumabiner Lightweight Folding Knife w/LED Light. Launce Barber and Tom Stokes designed the patented Lumabiner as part of our innovative I.D. Works line of tools. It's a cool and organic shape that combines a knife and flashlight into a handy carabiner package.The useful little 1.625" drop point high-carbon steel knife blade with a Razor-Sharp cutting edge can be quickly opened with either hand using one of the dual ramped thumb studs. Just press the little black button and it's a powerful LED flashlight that is always ready when you need it. You can pack the Lumabiner on belt loops or D-rings with the carry carabiner (which is non-weight-bearing).
