The Benchmade 570-1 Presidio II is a modernized version of the legendary tactical knife that utilizes a lighter CF-Elite liner , a CPM-S30V powder steel blade and reliable shaft-lock blockade .Premium quality steelThe 94 mm long drop point head is made from premium steel CPM-S30V, hardened to 58-60 HRC hardness . The American powder steel is valued for its corrosion resistance, abrasion (high impact resistance) and long working life .When choosing a knife made from this steel, it is worth getting a diamond sharpener because sharpening with a standard ceramic saw stone can be very time consuming and ineffective. The knife has a perfectly guided cutting edge, a strong point and a concave cut that ensures aggressive cutting and good penetration. The Presidio II is practical and easy to carry, making it perfect as an edc knife.The blade is satin finished (polishing technique), giving the steel an elegant matt finish.Quick disassemblyThe knife is opened by a double-sided pin, making it easy for right and left-handed users to use. The convenient positioning of the pin also allows the knife to be used comfortably with gloves on.Safety during workThe knife uses Benchmade's flagship lock, the shaft lock mechanism, which is valued for its resistance to high dynamic loads, dirt resistance and ease of use. The strength and rigidity of the knife's construction is ensured by full steel liners of increased thickness.Lightweight and durable linersThe knife's profiled sheath is made of a special CF-Elite material (carbon fibre reinforced nylon), which is much lighter and stiffer than, for example, G10 laminate.The handle is contoured and flares out at the base of the blade, creating a natural cross guard that prevents the hand from slipping on the blade and provides support for the fingers.The beveled cutters and small square protrusions emphasize the tactical character and ensure a stable grip of the knife. The knife can be carried discreetly in the pocket thanks to the clip mounted high up, which can be moved to the other side.
