Imvho: Kershaw < SpyderCo < ZT. That being said, Kershaw and ZT are both lines of the same manufacturer, comparable to Magnum knives and Böker plus which are both made... Erm... by Böker... (And some subcontractors which do the majority of stuff in a friendly nice country without minimum wages or laborer protection acts in the far east. If and how much that applies to Kershaw: I simply do not know. But they have some knives in price ranges which make me suspicious.) -- Urban EDC philosophy: Getting things done for yourself and others.
