Designed by legendary knifemaker Ken Onion, the Zero Tolerance 0350TS is the ultimate in utility, durability, and portability. Equipped with the patented SpeedSafe assisted opening mechanism, also designed by Onion, it's a cinch to quickly deploy. The black recurve drop point blade is 3.25" long made of S30V stainless steel Tiger Striped with Tungsten DLC (diamond like carbon) coating, which reduces friction and adds hardness.
