I would have no problem spending $200 or more on an EDC knife. Hell I carry a $2500 pistol every day so why not. That being said I have carried a $70 Spyderco Endura II for almost a decade now and I'm only 27. It does everything I ask of it and see no point in replacing it. I lost one a few years ago and I replaced it with another. I guess I don't punish my blades enough to justify more money than that on a pocket knife. Anything that boarders on abuse and I reach for an inexpensive (Cold Steel or the like) fixed blade.
