At this particular moment. . .for "Productions" it's hands down Microtech. I'd love to toss in the Cutter Knife & Tool Brend #2 DA but I haven't laid hands on one (so I'm relyin' on what masterchef is claimin' ~ simply cuz. . .that boy knows his bladeware !). I've had and do have several TiNive auto's. . .and they too are very very nice !
As far as "Customs. . .
That's a hard one. There are so many fine auto makers on the slate today ! I throw out a few that I quite enjoy. . .
Charles Dake, Jim Minnick, Larry Chew, Harold Corby, Brad Duncan, Alan Elishewicz, Mel Pardue, Nathan Clark, Jeff Harkins, Jerry Corbit, Darrel Ralph, Michael Vagnino, The Vallotton's. . .
WOW. . .and the list goes on.
