Scuba/Demo SSD89


The SCUBA/DEMO knife is a reproduction/replica of one of the rarest Vietnam military knives ever made to date.  Of the original batch of 39 knives made, only 1 out of the lot has survived till this day.  SOG has revived this knife by producing a copy that is made as close as possible to the original knife, except for a few shape changes.  The fact that it is sharpened on both sides makes it illegal to own in some states and countries.  It can’t really be classified as a ‘dagger’ because the area forward of the serrations (aka teeth) is not sharpened.  So basically it is a normal knife with sawback teeth on the other side, much like a Rambo style knife.  This very design is a very unique and purposeful one, and an interesting one at that.  Originally designed during the Vietnam War era diving knife, the SCUBA/Demo has a straight edge to cut, and a serrated edge to saw through thick rope.  Nevertheless for those lucky enough to own it, it is a sight to behold.  The leather handle with brass makes this knife a very handsome and classic ‘Vietnam era’ knife. Another must have in the SOG collection.  It is also the only old model that has its model name engraved on the knife “SCUBA/DEMO” on center right of the blade. Note: The first 250 SCUBA/DEMO knives produced were number stamped on the pommel (see last pic).
