I didn't read all of the threads yet, so I don't know if anyone has mentioned this, but regardless of the designer, I would REALLY like to see ZT come out with a high end, composite bladed FIXED BLADE.
I'm not too fond of the ZT lineup of current fixed blade knives, but they've come out with some rock-star folders, so I'd love to see them use some of the amazing designs out there to come out with a small multitask fixed blade, maybe a fighter along the lines of the Terzuola CQB or the DDR X-ray 18 Fixed blade, then maybe a big chopper. All, or none, could be composite blades, but I would be really happy to see them focus some of their efforts on making some really cool fixed blade knives.
ETA: WAIT......WAIT WAIT! Just a second. I've got it. I know I said I'd like to see some nice Fixed Blades, but I thought of one collab that I would just freak out over. I would love to see a big hard use Wharncliff style blade. SO --- Yuna!!!
I would LOVE to see Zero Tolerance get together with YUNA Knives and make a ZT version of the Zen or the Zombie Slayer...........in ZDP-189 or M390.......OR A COMPOSITE BLADE. Damn, that would be ridiculously awesome!!!
ETA AGAIN : Tradestar, didn't see that you said Yuna..........You're damn right, though. His Type S Beasts fit the ZT mold perfectly. The Hard 1 and the Assassin are both badass knives. I've been trying to save up and decide between getting a Zen or a Hard 1, but for a ZT collab, I think the Zen or the Zombie Slayer would be PERFECT. In fact, I think the Zombie Slayer would take the cake. Its such a chunky blade, but with that huge straight edge, it would be perfect for the ZT treatment.
After seeing some other's posts, I've gotta say I'd like to see Valloton or Shirogorov ( yes, I know the Sinkevich is similar to a Shirogorov, and thats why I WILL be getting it ), Curtiss wouldn't be bad either.
