ExtremaRatio - Ant Black Knife - N690 - Folding Knife
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 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 Black version utilizes Böhler N690, hardened to 58 HRC for the best balance between edge retention and toughness, a type of steel used by Extrema Ratio for most of its knives.
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.

ExtremaRatio - Frame Rock Titan - Black DLC - folding knife
The Extrema Ratio Frame Rock is a new knife, based on the Ti-Rock project, a successful frame-lock knife made by Extrema Ratio in 2016 exclusively for Coltelleria Collini.
The Extreme Ratio Frame Rock is characterized by the titanium handle that offers great resistance while being very light. The integrity of the frame-lock locking system is guaranteed against wear by an easily replaceable hardened steel insert.
Unlike its drop-point predecessor, the Rock frame has a spearpoint blade 75 mm long, 6.0 mm thick, equipped with fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available in black finish with DLC or satin finish.
To make the opening even more fluid and free of uncertainties, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to release the blade from the closed position.
The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside. The large, solid handle and the well-proportioned blade allow this knife to tackle demanding tasks. Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. It is supplied inside an ABS box.
Intended use: collection / CQD
Type of production: industrial
Blade: in N690Co stainless steel
Blade treatment: Black DLC
Country of production: Italy
Handle: in Titanium, machined from solid, with integral Frame Lock closure system with removable hinged and safe made of stainless steel

ExtremaRatio - Ant Rescue Red Stone Washed Knife - M390 - Folding Knife
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.
