With more then 40 years of Professional Diving experience between us, its only natural we would at some point design a Dive tool.. It has taken a need by our Nations Elite Warriors on the tip of the spear to get us motivated to do it. For that we are honored.  This is a Tool cause dive knives are stupid and any Professional Diver/Combat Diver will tell you a pair of surgical sheers is better than any dive knife. This Tool was designed to cut things you would cut underwater, around the water and in most rescue situations. The full blade edge is serrated and the tip is ground to a 40 thousands land (.040) as a very effective pry tool. The Ring is for retention, strike enhancement and is sized to fit a dive glove or work glove.
