The Benchmade Infidel 3300BK is an automatic tactical knife , with D2 tool steel blade , large folding knob and milled flying aluminium handle .The Benchmade Infidel 3300BK is a large automatic OTF (front) knife designed for uniformed services and everyday use.Tactical bladeThe knife has a narrow dagger profile dagger blade, made from hard D2 tool steel, hardened to 60-62 HRC . D2 is the most corrosion-resistant carbon steel, characterized by high wear resistance, long life and aggressive cutting .When choosing a knife made of this steel, it is advisable to obtain a diamond sharpener, because sharpening with a standard ceramic saw stone can be very time consuming and ineffective.The blade has two cutting edges and an aggressive tip , so it penetrates easily and has good cutting properties. The blade is covered with black Teflon , which partially protects the blade from scratches and corrosion and emphasizes the tactical nature of the knife.Instant decompositionThe blade is unfolded by moving the serrated slide forward , folding only requires pulling the slide in the opposite direction. The knob has a deep etch so the knife can be handled in gloves.Reliable and safeThe blade can only be extended and folded when the slider is fully retracted, making the knife safe to use and carry. The whole process is instantaneous and, most importantly, safe. Because it is blocked in up to 3 places after the blade is opened.Ergonomic handleThe comfort and ease of use of the knife is ensured by the solid handle made of 6061-T6 flying aluminium . The handle has a profiled shape with a milled surface, which guarantees a perfect grip in the hand and prevents the knife from slipping.The Benchmade Infidel 3300BK has a high-mounted clasp compatible with the Molle system (with the possibility of moving it to the other side) for discreet carrying of the knife in the pocket and for attachment to a belt or backpack. The set also includes a nylon sheath with Velcro closure.TECHNICAL SPECIFICATIONSSheet informationBlade profile Dagger / DaggerSteel hardness [HRC] 60-62Blade lock type Automatic lockKnife type foldingKnife type automaticOpening type automaticSteel type carbon - D2 Additional informationClip for transport is providedCasing material metal - anodised aluminiumSheath material corduraCorrosion resistance highDull resistance very highSheath is providedCutting type flat Opening aid yes, spring loadedApplication (intended use) tacticalDimensionsTotal length [mm] 225Blade length [mm] 99Length after folding [mm] 127Blade thickness [mm] 3.5Weight [g] 139
