Extrema Ratio BD1 R pocket folding knife
Extrema Ratio presents a folding knife designed for lightness, inspired to the traditional Italian knives with a compact size coupled to the “Razor” opening system
The Extrema Ratio BD1 R is a new knife designed for lightness. It is characterized by a very slim profile with a focus on lightness, without renouncing the usual Extrema Ratio toughness and reliability, also thanks to the black anodized, Anticorodal grip.
The modified spearpoint blade has a satin finish and is made in Bohler N690 steel hardened to 58 HRC, 2.75” (70mm) long, 0.1” (2.5 mm) thick, with a plain sharpening and a faux edge on the first third of the spine. The blade is deployed by the usual “Razor” tang extension which enables effortless ambidextrous operation. A simple yet sturdy liner lock system holds the blade open.
The primary safety is provided by the liner-lock system of the blade.The lack of an added safety system instead is a choice made according to the purpose of the knife and helps minimizing weight by removing anything that’s not strictly indispensable.
The reversible clip with lightening holes contributes to maintain the weight of the knife to a minimum. Scallops milled in the handle help to guarantee a solid grip on the knife and facilitate grip transitions.
With an overall length of 6.7” (170 mm) and a weight of just 2.7 oz (75 g) the Extrema Ratio BD1 R is an extremely light and slim knife which makes it an ideal EDC choice.
