Fixed -- I actually only own one factory/production fixed blade, a BK&T, Jerry Fisk designed BK-5 Magnum Camp -- mine doesn't have a Jerry Fisk convex edge, though. If I can pick something mid-tech, then it would have to be the CF/DLC mid-tech Crowfoot I bought from Rob Simonich at the 2002 SouthEastern Show.
Folder -- I think I'd have to choose the Spyderco/Terzoula Starmate as favorite, even though I think that the ParaMilitary is a better knife.
