After all these years I've finally decided that zero tolerance is my favorite brand. Spot on fit and finish,good choice of materials,great ergonomics(for me),really nice pocket clips,And they're just plain cool looking.(to me)
ZT used to be my favorite until I found out about Spyderco. Zero Zt's that I have are slicers and they are all Tactical looking.... And while that is neat it's not useful. I don't use knives for Tactical reasons. I don't use them for protection, or fighting. I use them for cutting.
Sure zt's are sharp and they cut things, but they are not slicers as the geometry is more Tactical. So while zt has many great features as you've mentioned and I love them for those reasons you mentioned.. But they need to make actually useful knives that are good slicers. This is why I like spyderco. Cause the geometry allows for less friction when cutting.
My realization was a more recent one as I keep buying more of them and compare them to the zt's when cutting all sorts of things. My 0850 is sharp af but didn't slice some rubber tubing at work when I needed it, where as the Spyderco military made short work of it.
I think zt markets more to fire arms market for Tactical folders. It's crucial to sales for zt.
So I went from zt because of the quality and materials and action etc. Then switched to spyderco as my main users. Still love those zt's tho.
Spyderco is offering the same quality, but far more options and blade materials including super steels like M4, maxamet, zdp189 etc at affordable prices. Not to mention they are sharpened better than most other brands these days. No blade replacements tho, and the warranty wasn't as good but recently changed to allow disassembly and they removed red loctite on new production. Just need to be able to buy a blade for a fee, that would be great.
