The Extrema Ratio NK1 is a tactical neck knife made from one solid piece of Bohler N690 stainless steel. This highly corrosion resistant steel has a very high hardness as well, leading to better than average edge holding capability. The handle is close to the sharpened edge and presents a curved recessed area on the lower side to place your index finger and to avoid injury when pulling the knife from the Kydex sheath. If you need a solid neck knife with a comfortable handle, look no further than the Extrema Ratio NK1. See it now at www.knifecenter.com.
