Extrema FRAME ROCK Framelock Folding Knife, Bohler N690, Titanium Blue

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. incorporates a mechanism that allows the user to adjust the force needed to free the blade from the closed position thanks to a screw. A counter screw secures the adjusting screw in place after it has been set to the desired position.

The reversible clip with lightening holes is designed to allow deep pocket carry, with as little as possible of the knife visible from the outside. Scallops milled in the grip facilitate one handed opening via the classical ambidextrous stud on the blade, and facilitate grip transitions.

The knife overall length of 7.1” (181 mm) places it in the range of medium sized folders and the solid, large grip and well proportioned, stocky blade allow it to tackle heavy tasks without fear of failure.
