* 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.

The “Shop Built” line by Ansø of Denmark was created to offer Jens Ansø's original designs in a more accessible and reproducible form than his custom knives, which are traditionally produced in extremely limited quantities. All “Shop Built” models are designed by Jens Ansø in Denmark and made by his team of skilled craftsmen, who take care of every stage of production with great attention to detail.
This product range maintains the same design philosophy, build quality, and craftsmanship that have made Ansø's work famous, but with a more structured and sustainable production process, designed to satisfy a wider audience without compromising on high-quality materials and finishes.
The AROS model
The AROS is a compact and versatile folding knife, designed as a utility tool for everyday use (EDC). Designed by Jens Ansø, it stands out for its unique design and precision engineering, designed to offer superior performance in everyday activities: from opening packages to more controlled cutting and carving.
The AROS features an innovative integral monoblock frame on each side, incorporating pivot screws, button lock, clip, and lanyard hole in a single precision-machined piece. The two parts of the handle are securely joined with titanium screws on the back, ensuring strength and a clean line.
The 2.5-inch (64 mm) blade now features a hollow grind, a new feature that further improves cutting capabilities while maintaining a slim and elegant profile. The flipper tab is designed to ensure quick opening and, once open, also functions as finger protection. The careful shaping of the blade tang contributes to a comfortable and secure grip, confirming Ansø's focus on functionality and user experience.
