ZT does not appeal to me at all. It's like they're confused about what they're trying to be. A lot of people will disagree with me and that's fine, it's just my opinion. They honestly just seem to come up with the flashiest pocket jewelry they can, throw some bearings on it and make it a good flipper and it'll sell.
They used to be folding pry bars, but that was their niche and it worked. If that's what you needed or wanted, you got it and it worked. They didn't cut well but they were strong as hell and did do cutting tasks well enough if you were patient with it.
Now they aren't overbuilt, and they still don't really cut that well. Their S35VN is pretty disappointing in the edge retention department also. I'm glad they're moving away from it. Even still, they aren't over built and some of them don't really cut that well....so what purpose do they serve? If all you do it cut strings off your jeans and slice an apple or steak at dinner time, then it'll do just fine. But that's not what my knives get used for.
I also dislike that EVERYTHING has to have bearings. If anyone has actually used a bearing knife outside...you know...to do actual work - they're AWFUL. They will get dirt in the bearing race and they will instantly seize up or become so gritty that you're scared to open it and close it before washing it out. I much prefer washers because they're basically immune to getting trash in the pivot, you only have to worry about the detent.
Again this is just my opinion on the matter but I wish they'd move to more practical designs with actual use being the sole priority. I'm not into flashy pocket jewelry or a fidget toy to flip all day.
I'll reiterate again, this is just MY opinion and you're free to disagree. I honestly couldn't care less if you disagree and think I'm 100% wrong, so flame away.
