I EDC a William Henry Tom Brown Quest "survival" knife. I think it is the largest folder that W/H makes. I modified it to suit my needs. I added a pocket clip and a damascus blade. The core of the 3 1/8" blade is ZDP=189 hardened to 67Rc. The 6/4 Ti handle has been skeletonized on the inside to reduce weight. The thing weighs 59gm. The button blade release works a lot like the axis lock, but it is not ambidextrous. This is a lot of knife in a small package.
