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, satin blade 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 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.
