BF1 CD Black Aluminium, Black MIL-C is a slim, ultra-lightweight folding knife at just 88 g, and easy to carry—hallmarks of Extrema Ratio's Basic Folder series. It is both an excellent tool and an exceptionally efficient E.D.C. folder. Its cutting capabilities are surprisingly impressive given its compact size.
N690 - corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with molybdenum 1.10% (Mo), vanadium 0.10% (V) and cobalt 1.50% (Co) for structural uniformity. Features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. It achieves a hardness of 57-60 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - an extremely sharp Drop Point with a pronounced belly, coated with a scratch-resistant, non-reflective matte MIL-C-13924 BURNISHING finish. The smooth Plain edge features a flat grind, providing durability, excellent cutting edge geometry, and extreme cutting performance. The blade is equipped with a dual-sided Thumb Stud for easy opening. A solid Liner-Lock mechanism ensures secure blade locking.
Handle - stainless steel liners and anodized aluminum scales provide both lightness and structural durability. The open-back design simplifies cleaning and maintenance. A robust, ambidextrous, bridge-shaped metal clip allows for discreet deep-pocket carry in the tip-up position (blade tip facing up). The clip also serves as a convenient thumb rest, especially for users who prefer a reverse grip.
