  1. Zero Tolerance - ZT0100 by Ken Onion - Black DLC CPM-3V & Black G10 - PRIVATE COLLECTION - knife

    KNIFE FROM A PRIVATE COLLECTION
    * Origin: Previously purchased knife from a private collection

    * Commercial Availability: Discontinued
    * Sharpness: Factory-sharpened, could be improved
    * Blade Condition: Minor cosmetic marks on the DLC finish due to age

    The Zero Tolerance 0100 is one of the first knives produced by Zero Tolerance, the premium division of Kai USA, which was launched in 2006 to develop professional tools for military personnel, law enforcement, and first responders. The 0100 model was, in fact, one of the first three fixed-blade knives in the original lineup, alongside the 0121 and 0150 models.

    The design bears the unmistakable stylistic signature of Ken Onion, the renowned American designer already responsible for numerous successes at Kershaw. The distinctive “S”-curved blade offers an unusual combination of cutting ability, power, and precision, making the ZT0100 suitable for both tactical applications and the most demanding outdoor use.

    For its construction, Zero Tolerance chose CPM 3V, a steel then considered cutting-edge for its strength and impact resistance, paired with a tungsten DLC coating and three-dimensionally machined G-10 scales. This combination helped solidify the brand’s early reputation as a manufacturer of “overbuilt” knives, designed without compromise for field use.

    Today, the ZT 0100 is a discontinued model particularly prized by collectors, as it is considered one of the knives that helped define the Zero Tolerance brand’s identity in its early years.
