Zero Tolerance claims that its knives are proudly “overbuilt”. Made of high-performance steels, such as ELMAX® powdered, they are intended for hard use. Originally specializing in military and law enforcement knives, the company has recently branched out into everyday carry (EDC) and premium knives as well. ZT teamed up with Rick Hinderer to design the top selling EDC knife ZT0566. Check out the ZT Hinderer in Blackwash™ here.
