Nice "little" ZT

Really love the look of this knife, feels great in hand, and cuts like an absolute boss. Not the best flipper action by far from ZT, but the positives outweigh that one issue.
My favorite everyday knife !

This is the most I have ever spent on a knife. At first I intended to just play with it and leave it in the box. Can’t do it. I carry it every where, every day, and I love it. Thought I lost it and was sick for two days until it showed up. Holds up great to everyday use. Silky smooth!
Gorgeous

This is my best looking, best flipping, most ergonomic knife.
A little too nice for me to take to work everyday because I don't want to beat it up or lose it but it is a great size for EDC.
Came perfectly centered and wicked sharp. The break in was rough and got worse before it got better, but now it has beautiful deployment.
Cheers!
An elegant ZT

This is a smaller more elegant and easily carried ZT. I love it, and may buy a second for when I retire.
You need a special tool to take it apart though available from Kershaw. Kind of annoying, but I love the knife overall.

I love this knife. it needing the STP tool kind of sucks and it should have came with it but that is really its only flaw. the blade to handle ratio is fantastic. it is a big blade in a small handle. I had to flip the bearing race washers because it was assembled too tight and left bearing divots in them but it is super smooth now. After it broke in it is a dream. Definitely one of my favorites second my 0640.
Great Knife, but needs a kershaw tool?

I love this knife, and am a big fan of zt's slimmer designs, as they are edc pocket friendly. I would agree with other comments that the flipper could be a little better, but I wouldn't call it an issue. have never got a 1/2 flip if you know what I mean. My only gripe is that it is $200+ knife and doesn't come with an adjustment tool. For that price tag it should be included. To add insult to injury, the tool is kershaw and not ZT, I know these are just names and are under the same umbrella (kai), but did add to the frustration of not coming with the tool.
Very good package

I love this knife! I haven’t had it long. But this knife has met all of my expectations for a slimmer knife with a longer blade. Highly recommended! Especially if you’re used to a bigger flipper, like Hinderer design, looking for something slimmer in your pocket. I consider myself an amateur knife enthusiast, but I think I can say I recognize good quality when I see it. And this knife is definitely good quality.
Love everything about it!

I bought this knife mid June and have loved it so far. I like how ZT went with CPM 20CV for their knives this year (similar to M390). It is very classy looking with the bronze titanium handles (a darker earthy tone, not shiny like the CRKT Ripple 2 bronze). I think it is a good light weight knife and the blade to handle ratio is very nice as it doesn't seem like a big knife in your hand. Great ergonomics and fantastic action on bearings. Only negative is that the pivot tool is not included (should be included in a $220 knife but understandable if not included with cheaper Kershaws). Would definitely recommend and now comes in all black and blue titanium sprint runs!
New EDC!

This knife is fantastic! The ergos are great and the action is stellar. The blade is the best part of this knife. This thing cuts. The stonewashed flats and the satin grinds give it a polarizing look and the anodized scales look very nice in my opinion. The only downside is that ZT did not ship the pivot tool with the knife which I feel is a mistake, but I'm not too worried because I 3D printed my own. Overall, 9/10 and highly recommended
