The Benchmade 4170BK Auto Fact is a striking spring knife that combines the style of an Italian stiletto with the functionality of an edc knife and the reliability of tactical knives. American tool steel The knife has a slim 100mm long blade, made of elite CPM-S90V stainless steel, which is subjected to the optimal hardening for edc knives to a hardness of 59-61 HRC. CPM-S90V is a luxurious stainless steel with a very high vanadium and carbon content, which makes the blade unusually have excellent retention, and is highly resistant to abrasion and corrosion. When choosing a hard steel knife, get a diamond sharpener, as sharpening with a standard ceramic whetstone can be very labor-intensive and inefficient. Utility head The utilitarian spear point profile blade is coated with a black DLC (Diamond Like Carbon) protective coating. This hard-wearing carbon sheath, increases the external hardness of the steel, so it perfectly protects the blade from corrosion, wear and scratches. A head with this profile is an excellent choice for those looking for a knife for everyday use. On the back of the ridge transverse cutters have been made, allowing the finger to rest steadily while cutting. The thickness of the blade at its widest point is 2.8 mm, which is a compromise between durability and functionality of the knife in everyday work. Spring-assisted The blade can be conveniently and quickly unfolded with one hand using the locking slider on both sides, so the knife is ready for use in no time. Auto Axis-lock mechanism, valued for its high mechanical strength, resistance to dirt and ease of use, is responsible for the safety of work. The knife uses an additional lock to prevent accidental unfolding of the blade during handling. Aluminum handle The knife has 6061-T6 aircraft aluminum liners attached to steel reinforcing inserts. The element that attracts the attention of any knife enthusiast is the carbon fiber inserts and polished spacers, discreetly emphasizing the luxury character of the knife. Thanks to precision machining, the knife fits perfectly and feels great in the hand. The semi-open handle design makes it easy to keep the knife clean. Convertible clip Discreetly carrying the knife in your pocket is made possible by a high-set clip that can be mounted on either side of the handle.
