This Ka-Bar 1217, made in 1991, is a commemorative knife designed to mark the 50th anniversary of the Japanese attack on Pearl Harbor on December 7, 1941. This surprise attack, conducted by the Imperial Japanese Navy, aimed to destroy the U.S. Pacific Fleet and prevent a rapid response to Japanese expansion. The raid claimed the lives of about 2,400 people, including military personnel and civilians, and led the United States to enter World War II, declaring war on Japan the following day.

The Ka-Bar 1217, with its high-carbon steel blade and leather ring handle, has the same design as the legendary Ka-Bar knife used by U.S. soldiers during the conflict. The blade is engraved with the 50th anniversary logo and a symbolic image of Pearl Harbor, making the knife a collector's item and a tribute to the historical memory of the event. The Ka-Bar 1217 is not just a tool but a mark of honor and respect for the victims of the attack and the heroes who contributed to the victory of the United States during World War II.

Unlike the standard models, here we have engraving from the right side of the blade, hand-molded leather washers with an aged look, and even the scabbard is made like the 1940s models, with darker leather and steel staple points in addition to the traditional contrasting cream-colored stitching.

T4000S is a reworking of the Japanese Wakizashi short sword that the Samurai carried at all times in contact with the body. It is a timeless tactical tool that does not follow any fashion but faithfully respects the Extrema Ratio philosophy aimed at fulfilling all functional requirements.

This model continues Extrema Ratio's purest Tanto series designed especially for lovers of the Japanese blade profile, who do not want to give up typical tactical accessories such as textile sheath and special polymer handle. The blade is made of Bohler N690 steel, heat-treated to a hardness of 58 HRC.

The handle, in black coloring, is made of Forprene, an elastomer whose exceptional resistance to extreme conditions makes it part of the "NATO standard." The black-colored Cordura scabbard is and equipped with a MOLLE system that allows it to be carried on tactical vests and general belts and ensures that the razor-sharp blade can be carried in total safety by protecting it from shocks that could reduce its efficiency.

In designing the Belone, Danish Jesper Voxnaes started from typical lines of the Italian regional tradition, perfectly reworked according to his modern, minimalist style that has made him famous worldwide. The result is a light, tapered folding knife embellished with refined details, such as the holes in the back of the handle.
The Böhler M390 Microclean steel gives the Belone excellent cutting qualities, and the ball bearings make it the fastest flipper opening, perfectly integrated into the overall design. The carefully crafted ergonomically designed handle has an anodized titanium frame enclosed between thin carbon fiber folders. The Belone's clip is attached to the spacer so that the knife disappears completely into the pocket, maintaining maximum discretion.

The Ant is the most compact among Extrema Ratio's folding knives. Despite its small size, this model features an extremely sturdy, durable, and reliable structure.

The Ant Rescue, unlike other versions, has a cheek piece in red coloration that allows the operator to more easily locate the knife in case of a fall. This version is equipped with a specific serration that allows cutting ropes and even high-tensile aramid materials. Moreover, this model has a tapered tang that serves as an emergency screwdriver. The Ant Rescue has been developed according to the needs expressed by the "Italian Army Alpine Troops School".

The handle is made of two different elements: the cheek piece crafted from anodized anticorodal aluminum and the hardened steel frame which also serves as the blade lock (Frame Lock System). This mechanism involves a part of the frame bending inward to firmly secure the blade in the open position, enhancing the user's safety during the knife's use.

The tang features a hole for the insertion of a lanyard, and on the right side of the handle, there is a steel clip that allows for concealed carry in the pocket.

The Ant is available in 4 versions with two different types of steel, both provided by Böhler, an Austrian company with which Extrema Ratio has been collaborating for over 20 years, using its highly esteemed materials for the production of its blades.

For the Stone Washed M390 version, Extrema Ratio uses Böhler M390 steel, thermally treated to 61 HRC, which, thanks to a powder metallurgy production process, ensures cutting effectiveness, wear resistance, and oxidation resistance over time.

The blade is sheep foot-shaped and has a small hole on the top part to facilitate opening. Its particular structure, with a straight edge, allows the user to comfortably rest their fingers on the back of the knife and use it with ease.

Oniro is a knife that was born out of Viper's first collaboration with Denis Simonutti, as well as the first Viper folding knife to employ the crossbar lock, a safe and practical locking system to use.

With compact dimensions and an ergonomic design, this knife stands out for its adaptability and reliability. Ribs on the handle provide a firm and comfortable grip, allowing precise control in any situation. The Magnacut steel drop blade of this knife offers impeccable cutting precision, making it an indispensable tool for any task.
