Zero Tolerance Knives, often abbreviated as ZT, is a brand of high-performance knives that are designed and manufactured by Kai USA Ltd., the same company behind the popular Kershaw brand. Zero Tolerance was established in 2001 with the goal of creating premium knives that cater to the needs of knife enthusiasts, collectors, and professionals who demand the best. Over the years, ZT has built a reputation for producing knives that are known for their exceptional quality, innovative designs, and attention to detail.

From its inception, Zero Tolerance has collaborated with renowned custom knife makers and designers to create unique and functional knives that blend style with durability. This approach has enabled the brand to stay at the forefront of the knife industry, introducing new materials, technologies, and designs that set the standard for others to follow. Today, Zero Tolerance is recognized as one of the leading premium knife brands, with a loyal following among knife enthusiasts and professionals who appreciate the brand's commitment to excellence.

Steel and Materials Quality

Zero Tolerance is known for using high-quality materials in the construction of their knives, with a focus on premium steels that offer exceptional strength, durability, and corrosion resistance. Some of the steels commonly used by ZT include S30V, S35VN, and 20CV, which are all high-carbon stainless steels that provide a perfect balance of hardness, toughness, and wear resistance. For example, the S30V steel used in the ZT 0456 model has a hardness rating of 59-61 HRC, making it an excellent choice for heavy-duty use.

In addition to premium steels, Zero Tolerance also uses other high-quality materials such as titanium, aluminum, and carbon fiber in the construction of their knives. These materials are carefully selected for their strength, lightweight properties, and resistance to corrosion, ensuring that ZT knives can withstand the rigors of heavy use and harsh environments. The use of these materials also enables ZT to create knives with unique designs and features, such as the ZT 0999, which features a titanium handle with a carbon fiber overlay.
