Benchmade 4400BK Casbah is a lightweight automatic knife , equipped with a CPM-S30V stainless steel blade , a discreet unfolding button and linings made of durable G10 laminate . American tool steel The knife has a usable drop-point blade with a length of 86 mm , made of American CPM-S30V stainless steel . S30V powder steel by Crucible Industries is hardened to the optimum 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 was finished with a satin finish (polishing). 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 blade with a useful drop point profile is covered with a layer of black Teflon, which protects the blade from minor scratches. The knife has a gently marked belly of the blade and a strong point. A blade with such a profile is an excellent choice for people looking for a knife for everyday use . On the back section of the spine, transverse cutters were made, allowing for stable finger support during planing or precise cutting . The thickness of the blade at its widest point is 2.9 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 comfortable and quick unfolding system . 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 starting a strong spring. Folding the blade requires pressing the button again and manually retracting the blade. Such functionality makes the "automatics" very popular among soldiers, employees of uniformed services and EDC enthusiasts. The enlarged release button is embedded in a milled cutout, so it does not protrude above the handle. When using the automatic knife, it is recommended to exercise extreme caution and prudence. Reliable lock The flagship Benchmade mechanism, the double-sided Axis-lock lock , is responsible for work safety , valued for its enormous mechanical strength, resistance to dirt and ease of use for right and left-handed users. Comfortable grip The Benchmade 4400-1 Casbah has molded grips in blue Grivory plastic . The glass-epoxy laminate used is characterized by low weight, high mechanical strength, resistance to water, temperature changes, as well as the action of many acids and solvents. The contoured shape combined with the undercut for the finger, transverse milling and the rough texture of the material ensure excellent grip of the knife and comfort of use. The discreet carrying of the knife in the pocket is possible thanks to the high-mounted clip with the possibility of attaching it on both sides of the linings.
