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, always useful. These unique tools make up our growing I.D. Works® line. Put them to use, enjoy them, and always remember what inspires you!
