Italian company created in 1997, Extrema Ratio evokes for many, the "Rolls Royce" of cutlery, and has become for the operational units and the connoisseurs of the whole world, synonymous with excellence in the field of tactical knives, these being the very best in terms of strength and endurance.
If you have to choose just one knife, whether for military and tactical use or for survival, choose an Extrema Ratio Knife!
The Extrema Ratio Frame Rock is a new knife, based on the design of the Ti-Rock, a successful framelock custom made knife that Extrema Ratio has realized for a renowned Italian distributor.
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 9.6 oz (270 g) making it quite light for such a robust knife. It comes with a special ABS case.
