The Extrema Ratio Frame Rock is characterized by the titanium grip that offers great toughness and yet is very light.
The frame lock integrity and duration are guaranteed against wear by a heat-treated steel insert that can be easily replaced.
Differently from its drop-point predecessor, the Frame Rock has a spearpoint blade, 3” (75 mm) long, 0.23” (6.0 mm) thick, fullered for further lightness. The blade is in Bohler N690 steel, heat treated to 58 HRC. It can be had in black with DLC treatmet or stone washed finish.
To make opening even smoother and effortless, the blade pivots on ball bearings. This mechanism allows the user to adjust the force needed to free the blade from the closed position thanks to a screw.
The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside.
The grip, large and well proportioned and the stocky blade allow it to tackle heavy tasks. The Frame Rock weighs just 6.7 oz (190 g) making it quite light for such a robust knife. It comes with a special ABS case.
