Indicative of several South Pacific Island peoples, the design of the so called "Shark Tooth" Sword was both unique - and vicious. Made of regional hard woods, fire heated for additional hardness, a typical weapon was roughly 3 to 4.5 feet in length. Cut from on continuous piece, a handle was sometimes fashioned - often with a crude form of "D"-Guard for basic hand protection. The flattened blade was roughly 1 to 1.5 inches in width. A groove was carved along the blades perimeter. Fitted along the perimeter was inserted small shark teeth (with Mako and Hammerhead being highly sought after for use). Resembling a "chain saw", the natural razor sharpness of the Sharks teeth, created an effective weapon. Used roughly as a hacking and chopping weapon, this Sword could effectively sever limbs and cause almost always fatal wounds. The large distribution of The Shark Tooth Sword design wad possibly through inter-island trading. They are thought to date from the 7th Century A.D. and carried well forward into the 16th Century.
