Extrema Ratio Knives

Extrema Ratio Kukri for sale is 14 7/8th inches in all. The Extrema Ratio Kukri is based upon the design of the Nepalese all-purpose knife that found its origin in ancient Greek curved-blade swords. This contemporary version features a combination grind blade with a hollow grind close to the handle which is used to produce the sharp edge without sacrificing the overall thickness of the back of the blade. Whereas, the tip is flat ground and well-angled for maximum penetration. The durable edge is a result of the Bohler N690 steel which was used for the blade steel. The 9 ½ inch blade has Mil-C-13924 Burnishing for the black finish. These knives are made in Italy and use a grip polymer called Forprene which provides a very sure and comfortable grip even when wet. Buy the Extrema Ratio Kukri for $359.99.
