Abusive cutting seems to be a main design parameter for this knife. Sure the S30V steel can handle narrower edge angles for most uses. I wouldn't go below 30 deg inclusive because at that point you're better off getting a smaller knife that handles more like a pocket scalpel. Weight, balance, rotation and control are big indicators of what the blade was designed to do best. IMO, the ZT0300 is too cumbersome to fill that role as well as the more traditional designs.
Uses? Mine loves a steady diet of old speaker cables, CAT 5, parachord, rope, tree trimmings, fruit, jeans, steak, boxes, sandpaper, and junk mail. I've cut all of the above and it still pops hairs. Tougher stuff is on the horizon for me: razorwire, cans, hoses, ...
After the factory edge wears down a bit I plan to differentially sharpen the blade (cf:
Joe Talmadge). The inside of the recurve will be a slightly rough, micro-serrated edge for cutting harder, thicker materials. The belly up through the tip will be more finely polished for cutting softer, thinner materials.
