Customer Reviews

Awesome assisted mechanism and great looking blade finish
Christian A. on Jul 2, 2021

This was the first folding knife I ever bought. I got some others since and I still think this ZT is something special. It looks great - especially the blade finish - and cuts extremely well. The price is kind of a bargain for a knife of this caliber with CPM-20CV steel and G10 handle. I particularly love the assisted opening. The blade just explodes out of the handle when you use the thumb flipper. It is a little bit on the heavier side and it feels solid and comfortable in the hand. Great knife whether it's your first or your last. By the way, I used this as my EDC for several months until I got a Benchmade Bugout. It is a bit large but comfortable in the pocket and works great as an EDC.

Shane E. on Sep 25, 2022

One of the three knifes I mainly carry, this being the most common of the three. Gets hair splitting sharp and stays that way for an impressive amount of time. Assisted opening is smooth as long as you keep it clean. I hardly notice it in my pocket for how big of a knife this is. The shape of the blade allows me to put my index finger on top comfortably for fine movements and cut. Quite literally my favorite knife out of my small collection, and for the foreseeable future, it will remain that way.

Needs purpose
Vadim P. on Feb 8, 2021

This is a great example of using top quality materials (CPM20 steel), great workmanship (no complaints), prestigious brand with a hefty price tag and to what end? This knife needs a purpose: it is not a slicer (coated blade makes sure of it), a bit bulky and heavy for an edc (in my opinion); not a quick to open/close (my Spyderco is much more responsive); not that great for wood work (flat grind not too conducive); It passes a paper test with flying colors and is great for opening letters, not sure what I'd use it for.
