Extrema Ratio's Ultramarine was designed with the Naval Experimental Diving Unit of the United States. This knife was made to be a versatile tool, especially for underwater operations, so there is no dangerous piercing tip to cause mishaps. It's an underwater, survival, and combat knife with a black burnished, partially serrated blade that's made of exceptional Bohler N690 stainless steel and the inside-hilt blade tang underwent a special process to prevent corrosion. This fixed blade knife set includes a carrying case, maintenance spray-can, a Cordura fabric ankle sheath, and two belt clips that makes separate use of the inner hard sheath possible.
