Glauca G1, an evolution of the Glauca model, has specific features designed especially for the renowned GSG9 department, a special unit of the Bundespolizei, which has officially adopted it. The handle, made of anodized anticorodal aluminum with tactical mud coloring, is equipped with a tungsten carbide rear glass breaker.

On the back are a stainless steel nail stripper that can be locked in the open position and a resealable rescue tool that allows the operator to make a quick emergency cut to free a possible casualty from their clothing. This second tool is also great for use as a belt cutter.

The blade locking system is the proven LINER-LOCK to which is added a second safety mechanism to be operated manually.

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.

Notes: safety mechanism both in opening and closing

Directly derived from military specifications, this fold has been developed to replace a fixed blade in use.

To achieve this result, very strong materials, high thicknesses and a solid and safe opening and closing system were used: the back lock.
The knife is equipped with a manual safety device which confers maximum safety in use and reduces the risk of accidental closure in manieradrastica.
The safety device, if inserted in closing, prevents the knife from being turned against itself in the case of subtraction.

Materials and workmanship:

All parts of the knife are machined from high-precision CNC machines, while assembly, adjustment and sharpening are carried out by hand.
The blade is made of cobalt N690 stainless steel, a steel with very high resistance to mechanical stress, cutting capacity, thread strength and corrosion resistance. The grinding is flat and the hardness is 58HRC.
The grips of the handle are in Anticorodal, an aluminum alega with high resistance to mechanical stress and oxidation.
The tang, in hardened N690, is an effective emergency crystals. All screws, pins and clips are in burnished stainless steel. The blade, the lever and the shank are covered with Testudo treatment, very resistant to abrasion and oxidation. The cheeks are black anodized.
