pocket knives

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.
