Another high-tech detail, developed by Bill and CRK, is the curved design of the joint between backspring and blade. What it does is similar what a cam does in a compound bow - when you open a knife the tension is relatively small and grows over a long way from 1 lbs up, reaches max and sets the blade in place. But the force required to close the blade is a solid 5+ lbs! So in other words: it's easy to open, but very secure and way harder to close (accidently). It might be not the first knife with this kind of approach, but CRK just nailed it with smooth traveling mechanism like no other maker ever before. And last but not least... I really like the "Idaho Made" and Harsey's signature are hidden inside handle slabs in pivot area. The only marking on the outside is a very small CRK logo... minimalism and class at its best!
