Yes.
Wait, wtf was the question?... Oh yeah, uh, none. :yawn: That seems to be the safe answer.
While none of my folders feel like fixed blades, the Spyderco K2 would be answer #2. It's huge; the lockbar sticks, sitting completely under the tang, but doesn't touch the presentation side. It's annoying to open at first, but after a while, I felt that the K2's eccentric design made
strengths out of tendencies I see as
flaws with other knives. Definitely the most solid feeling folder I've used. Not
fixed-blade solid, but solid. The Adamas, the Contego, the 0560/61, the Manix 2 XL -- all of them seem pretty tough.
Any high quality balisong. The breeden bali by mil-tac probably being the most robust.
:thumbup: I wasn't think of Balisongs as folders, but they certainly do fold, can't argue with that

. You've got two thick pivots, and it's
virtually impossible for the 'lock'/latch or handle to fail. There's plenty of fun ways to hurt yourself with a bali, but a good bali should hold up well. The only Bali I learned on was a BM Model 52, which isn't a great knife for hard-use. But I've seen plenty that are big solid knives -- the Alpha beast, and especially some of heavy-duty monsters by 29 Knives.
