* Inspected and Certified by our in-house laboratoryThe 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.

Rockstead - Shin - Honzukuri rolled ZDP189 & aluminum with ray skin - PRIVATE COLLECTION - knife
KNIFE WITHDRAWN FROM A PRIVATE COLLECTION

* Commercial availability: Difficult to find
* Sharpening: Factory edge
* Blade marks: None
* Handle marks: None
* Box: Present and complete, with outer box

Inspected and Certified by our internal laboratorySHIN in Japanese means ‘trust’.
The SHIN is one of the largest folders in the Rockstead catalog and showcases all the typical and characteristic elements of the brand: aluminum handle with a pearl-radiant design, hardened anodization at 400 Vickers, and an insert of high-quality stingray leather (Samekawa).
This is a durable knife with strong cutting capabilities that maintains its edge for a long time. Even when used for rigorous cuts, the blade glides securely thanks to its particular sharpening.
The blade indeed has a HONZUKURI sharpening, convex on both sides, following the tradition of Japanese swords; this makes it both very sharp and sturdy, allowing it to cleanly cut a sheet of paper even after 1000 cuts through a very abrasive and resistant hemp rope.
A faithful companion for life, in which to place the utmost trust.
