Coltelli e Spade

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.

Extrema Ratio developed the first knife of a new production line, called CONTACT.

It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. It has got a lower guard branch to protect itself from incidental cuts, upper jumping to improve grip, concave fuller along the length of the blade and a generous thickness blade (6.30mm) the now famous Requiem, revisited in proportions and in some technical features. The first of a new line of multipurpose knives.

The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. All other colors in production have got a blade with Stone Washed finishing. The handle is still in forprene. It is more assembled by the side screws but thanks to the shank in truncated cone-shaped stainless steel that is screwed to the bottom and goes to fit inside a special seat, which makes it solid. In this way the knife is well balanced. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.

The main shell is injection-molded in shockproof nylon. The secondary retention system is reversible for ambidextrous users. The blade is guided through the conception of the blade. To extract the blade, to pressure the trigger will be sufficient, thus releasing the safety that holds securely in the sheath. In the horizontal slits of the sheath of a system, which fixes the blade to avoid shaking noises when it is stored inside. The back side of the nylon sheath is M.O.L.L.E. compatible.

The textile part is reduced to its minimum and has got the classic two-button safety strap with a belt loop Extrema Ratio aims to reduce the size of the knife, but not saving on the structural strength and safety accessories.
