ZT 0990 Folding Knife

The ZT 0990 Folding Knife brings the spirit of one of Zero Tolerance’s most ambitious designs — the award-winning 0999 — into a streamlined, production-ready masterpiece. It captures the futuristic engineering and visual intrigue of the original while delivering real-world usability and everyday reliability. With its skeletonized steel frame, intricate construction, and high-end materials, the 0990 proves that innovation and strength can coexist beautifully in one striking design.

Inspired by the Iconic 0999

Originally an ultra-limited custom model, the 0999 became a grail knife for collectors worldwide. The ZT 0990 reimagines that legendary form in a more accessible package, keeping signature elements such as the exposed “floating bridge” at the handle’s spine, cutout windows near the pivot, and carbon fiber handle scales with a steel front overlay. Even the branding is subtle — instead of a logo on the blade, “Zero Tolerance” is elegantly debossed into the backspacer, a quiet nod to the original’s bold design language.

Precision Engineering, Proven Performance

Made in the USA, the ZT 0990 features a CPM 20CV stainless steel blade with a durable stonewashed finish that resists wear and hides scratches. Known for its superior edge retention and toughness, this steel ensures lasting performance in demanding use. The KVT ball-bearing system provides glass-smooth deployment with a quick flip, while a steel inset liner lock keeps the blade solidly in place. A reversible deep-carry clip allows comfortable, discreet tip-up carry for either hand. Every component is meticulously crafted, making the 0990 both a cutting tool and a piece of modern knife art.

With its futuristic skeletonized frame, premium steel, and unmistakable design lineage, the ZT 0990 is a fitting tribute to one of the most celebrated knives ever made — a chance for enthusiasts to finally own a legend.
