Now you can get the same great performance and design features found in the Model 140 Nimravus, in a true Tanto blade style. The 4.5" full-tang ComboEdge blade is ground from 154CM stainless steel and features a false edge that lightens the blade without sacrificing tip strength. The Blades are BK1 coated - Benchmade"s proprietary blade coating offering excellent corrosion resistance, which exceeds the ASTM-117 specification for saltwater corrosion resistance. BK1 is a poly-ceramic coating (a blend of polymers and ceramic). It"s thinner than the previous blade coating BT2, has equal to or better corrosion resistance (exceeding the ASTM salt spray standard) and unlike BT2 has much better wear resistance due to the ceramic. Additionally they have integrated a series of positive indexing notches in the spine for sure-grip blade control. One of the most important features of any fixed blade should be the sheath, and this one is no exception. The sheath may also be carried inside, or outside, the waistband. The versatility of the knife and its sheath design allows for carry and use in nearly any application that warrants a tough, mid-sized fixed blade.
