Knife withdrawn from a private collection - In like new condition - Never regrind - Checked and certified by our in-house Coltelleria Collini laboratory.

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 a titanium handle that offers great resistance while being very light. The integrity of the frame-lock system is guaranteed against wear by an easily replaceable hardened steel insert.

Unlike its drop-point predecessor, the Rock frame has a 75mm long, 6.0mm thick spearpoint blade fitted with a fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available with a black finish with DLC treatment or satin.

To make opening even more fluid and without uncertainty, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to obtain the release of 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 and solid handle and the well-proportioned blade allow this knife to tackle heavy tasks. The Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. Comes inside an ABS box.
