On December 19, 1941, in Eluet El Asel, about 400 men from the 1st Royal Carabinieri Battalion Paratrooper faced the assault of 4 battalions of Indian troops of the British Army. Jumping from their trenches by launching improvised devices, the "Desert Lions", as Radio London called them, made the defensive line impenetrable by allowing thousands of Italian-German troops to withdraw safely. This was the first page in the long history of Italian paratroopers.

The Tuscania Paratrooper Regiment asked that the Extra Ratio T911 be specifically made as a commemorative knife for its 80th anniversary.

The T911 is a medium-sized folding light and designed for professional use by military operators. It is equipped with a modified spear point blade, flat edge, in Bohler N690 cobalt steel heat-treated to a hardness of 58 HRC, for the best compromise between strength, ease of regrinding and thread hold. The blade is 76 mm long, 4 mm thick, has a stone washed finish and rotates around an adjustable pin which allows to obtain the best fluidity in opening. A brace allows you to lock the pin in the best position.

The handle is in Anticorodal aluminum alloy with high strength black anodized finish and is milled to facilitate the transition from "reverse grip" handle to saber handle.

The blade is opened by means of a pin operated with the thumb. The knife uses a liner lock type blade lock and a safe ensures maximum hold even during heavy use. The safety lever is colored red for better visibility and engages in an advanced position for more instinctive use.

In the handle are integrated a seat belt cutter with easily available and replaceable cutter-type blade, a tungsten glass breaker, a stainless steel knot loosener and a screwdriver for adjusting the pointing optics, in AISI 420 steel. The clip , reversible and fixed at the end of the handle, allows a very deep port in the pocket, for less visibility.

The knife can be dismantled for cleaning and maintenance. With a total length of 194 mm and a weight of 145g, the T911 is easy to wear both in uniform and in civilian clothes.

Notes: Opening KVT on ball bearings - Opening system Carson Flipper

The Zero Tolerance 0808BLU, with blue-anodized handle, is a sprint run built in a limited quantity.

The 0808 is a collaboration between ZT and custom knifemaker Todd Rexford and is based on his Cesium model. It features advanced-formula stainless steel and ZT’s smooth-as-silk KVT opening system. The 0808’s blade is built of Crucible S35VN stainless steel. This powdered metallurgy steel is extremely fine-grained so it can be sharpened to a razor edge. Added niobium and nitrogen enhance toughness to resist chipping and provide excellent edge retention. Yet it’s also easy to re-sharpen.

Opening is fast and simple with KVT. Caged ball bearings surround the pivot to make the blade quick and easy to open using the built-in flipper. With KVT, the 0808 is as easy to open as any assisted knife, but without the need for a spring.

The 0808GLD’s blade is paired with chamfered titanium handles that provide a solid, comfortable grip. The sturdy frame lock has a hardened steel lockbar insert to offer extra-secure, extra-solid blade lock up. The reversible pocketclip enables you to carry comfortably left- or right-handed.

This blue-anodized edition of the 0808, the 0808BLU, is a sprint run. Quantities are limited. Check with your local ZT dealer for availability.

The Zero Tolerance 0808 is our latest piece of pocket technology. It's a collaboration between ZT and custom knifemaker Todd Rexford and is based on his Cesium model. But the technology here isn’t circuits and wires. Instead, it’s advanced-formula stainless steel and ZT’s smooth-as-silk KVT opening system.

The 0808’s blade is paired with chamfered titanium handles that provide a solid, and very durable, grip. The sturdy frame lock has a hardened steel lockbar insert to offer extra-secure, extra-solid blade lock up. The reversible pocketclip enables you to carry comfortably left- or right-handed. Move over, iPhone. The 0808 deserves pocket space.
