Benchmade 9400 Auto Osborne is an automatic version of one of the most popular Benchmade knives, which uses a CPM-30V powder steel blade, lightweight anodized aluminum cladding and a double locking mechanism. Premium grade steel The knife has a satin-finished blade with a length of 86 mm , made of American CPM-S30V stainless steel . S30V powder steel by Crucible Industries is hardened to the optimal hardness of 58-60 HRC , which is why it maintains high sharpness for a long time, has high mechanical strength, and is also resistant to corrosion. Thanks to the high content of vanadium carbides , the steel is distinguished by high impact strength and abrasion resistance, as well as excellent cutting properties . The blade is covered with a layer of black Teflon, which protects the blade from minor scratches. When choosing a hard steel knife, you should buy a diamond sharpener, because sharpening with a standard ceramic whetstone can be very laborious and ineffective. Utility blade The wide blade with a tactical reverse-tanto profile has a matte satin finish (polishing) that perfectly harmonizes with titanium facings. Thanks to the use of a durable point, flat grind and a cutting edge with a gently rounded line, the knife easily penetrates and has excellent cutting properties . The thickness of the blade at its widest point is 3 mm, which is a compromise between the durability and functionality of the knife in everyday work. Instant unfolding The main advantage of the automatic knife is the quick unfolding system and instant readiness to work. Unlike models with an assisted blade, in an automatic knife, unfolding the blade requires only pressing the button, which is responsible for releasing the lock and activating the internal spring. Folding the knife requires pressing the button again and manually retracting the blade. Such functionality makes the "machines" very popular among soldiers, employees of uniformed services and EDC enthusiasts . The release button is embedded in a milled cutout, so it does not protrude above the handle. The knife has an additional lock that prevents accidental pressing of the activation button and folding the blade. The slider of the second safety mechanism is located on the back of the handle. When using the automatic knife, it is recommended to exercise extreme caution and prudence. Modern materials The knife has cladding made of anodized 6061-T6 aviation aluminum , which is attached to steel liners, responsible for the stiffness and strength of the structure. One of the main advantages of aluminum, apart from strength and the possibility of precise machining, is its low weight, which is necessarily associated with the comfort of carrying and using the knife. The profiled handle is wider at the base, which makes the knife grip comfortable and the hand will not slip on the blade during work. The aluminum insert made of purple anodized aluminum contrasts effectively with the dark color of the knife and undoubtedly attracts the attention of every knife lover. Reversible clip Discreet carrying of the knife in the pocket is possible thanks to the standard embedded clip with the possibility of mounting on both sides of the handle.
