production models?? i think benchmade, a large selection of models, priced reasnobly, excellent quality, the line includes some all time classic tactical knives imho (ie - AFCK, Stryker, 710, the bali's, 970 series virtually made emerson, and many others) a good knife imho, good factory warranty, cant go wrong with one imho....
spyderco is a very strong second (if second is the right term, spydie quality is world renowned) just more BM to select from
custom?? give me a crawford KFF, or one of the others ala point guard or falcon, etc - excellent knives w/out a long wait
emerson would be right up there but tooooo darned high $$ imho, $1500 or so, just not really worth it for a working knife imho, although i plan to get a CQC6 this year, go figure, huh, lol
