ULTRAMARINE N.E.D.U is a variant developed and purchased by the U.S.A. Naval Experimental Diving Unit. Conceived of as a work tool, not as a fighting knife, it was accordingly designed with a tipless blade. For greater quickness in drawing, the sheath comes without an upper flap. The inside-hilt blade tang undergoes a special cataphoresis process to prevent corrosion. The knife is supplied in a case with: a cordura fabric ankle sheath, two BELT-CLIPs allowing for separate use of the inner hard sheath, and a blade maintenance spray-can.
