Why You Should Buy
Zero Tolerance is one of the finest manufacturers of folding tactical knives in the world. Its products are of the finest materials made by American craftsmen.
In particular, the ZT0393 blade is made of CPM-20CV, an excellent choice in stainless steel. This stainless steel resists wear and under heavy use can hold an edge longer. I found this out during my test and evaluation.
The frame lock on the ZT0393 is very strong, as it is made from titanium. I proved this as I drove the blade through a 0.625-inch wooden board. The KVT ball-bearings makes the opening of this folder smooth and flawless.
