Here at Columbia River Knife & Tool® (CRKT®) we're inspired by great design. Our I.D. Works® products are not tools you will find anywhere else. We're motivated by design that is both inspired and functional, as created 500 years ago by painter, sculptor, architect, and inventor Leonardo da Vinci, who said "observe everything" in nature. We've partnered with the best and brightest designers of today who share this vision of putting functional art in your hand. They are organic and ergonomic shapes, sometimes whimsical, alway useful. These unique tools make up our growing I.D. Works® line. Put them to use, enjoy them, and always remember what inspires you! Our new Flux™ modular tool system is another creative design by Launce Barber and Tom Stokes as a part of our I.D. Works® tool family. It is a lightweight, high-tech system designed for people with active outdoor lifestyles. This exciting new system was named the 2009 Most Innovative Imported Design at the Blade Show in Atlanta, Georgia, when it was first displayed in May of 2009. At the core of the Flux system is the lightweight aluminum carabiner chassis which allows tools to be quickly selected, attached, and clipped on clothing and gear. Two chassis are available; one with dual rails which will hold any two Flux tools, and one with a single rail which provides a carabiner for any single Flux tool. Note: Flux carabiners are non-weight-bearing and must not be used as a climbing aid.
