My take on all of the new ZT releases (and the Kershaws too).
In general, I'm glad to see ZT returning to their roots with more functional, less flashy, less expensive, more-likely-to-actually-be-available-for-everybody-to-purchase, Made-in-the-USA knives. I do miss the crazy, flashy stuff, and the 0454 and 0801CF are the top two ZT knives on my to-buy list.
As far as the higher end limited edition ZT knives go, I will have no interest in them if only 250 are made and they immediately become unobtainable at MSRP. I refuse to pay $1500-2000 in the after/secondary market for a $500 0888. ZT should make those knives available first, and directly, to the ZT hardcore collectors ... the same way Ferrari and Microtech do. I'm on the verge of selling my entire Kershaw and ZT collection (it's BIG!) because I can't even obtain the high end collectible models, and because I'm tired of waiting a year or longer for a knife that may NEVER appear. Kershaw dropping out of the forums was a bad move too - that interaction directly with Kai/Kershaw/ZT really kept me excited about their products and upcoming releases.
On to the knives ....
0562CF - Nice! Like the return to function over form, and the more utilitarian design.
0562 - see above
0620CF - Another nice utilitarian design. Love the Emerson collab. Everybody needs to own a wave.
0620 - see above
0180 - boring
0102 - Looks cool! But woah, is it a $400 hatchet?
Kershaw has some nice designs this year. I like the car theme blackwash series (Manifold, Lifter, Starter), and the rest of their blackwash efforts. The Strobe is a cool design! ... except for those ugly grips. The new Cryos are very cool, as is the Olive Knockout, the Siege, and the Emerson models.
All said, if I'm able to actually buy an 0801CF and a 0454, then I might continue collecting Kai products. I've got the proper pre-orders and reserves in, but as we saw with the 0777 and 0888, that sometimes doesn't matter. Otherwise, if I can't even acquire the ZT and Kershaw knives I want, then I'll probably put my entire collection up for sale here soon.
fwiw, I also collect Microtech, Pro-Tech, Marfione customs, other customs and semi-customs, and I'm almost always able to get exactly what I want with those, and at a reasonable price too.
Note: Please don't take my negative comments about Kai as an attack. I'm simply describing what I don't like about their recent business activities. They might even lose me as a customer ... not that they'd care. I would, for example, have bought an 0777 0777M390, 0888, 0888MAX, etc, but apparently I'll just never be able to buy one at a reasonable price. I've consequently spent most of my Kai budget for the past year on Microtech and Pro-Tech, because I could easily get all of their new models.
