The 0350 has a S30V steel blade that is Tungsten DLC coated and a G-10 handle for a secure grip. S30V is both wear resistant and well as corrosion resistant. The 0350 comes with the patented SpeedSafe assisted opening system to release the blade fast and easy. Like all other ZT?s this knife is proudly made in the USA. Another feature this knife has to offer is its quad-mount, tip-up/tip-down, left or right handed pocket clip. Zero Tolerance had only a few things in mind when creating and designing their knives. They wanted to make them with top of the line materials as well as being able to stand up to heavy-duty use. A lot of their knives are in collaboration with top knife makers such as Rick Hinderer, Todd Rexford, Jens Anso and Dmitry Sinkevich. Zero Tolerance initially only produced combat knives but have since added a variety of everyday carrying and premium knives, built with the same ?OVERBUILT? designs as their knives that are tailored towards military and law enforcement.
