ExtremaRatio - Frame Rock Titan - Black DLC - folding knife

Item n. ER-FRTI-BK

Quick Overview

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.
