17th-18th century, of classic form which evolved into the navaja. 4 1/8” (4.18”) length with curved edge, recurved back, and broad back fuller above the wedge section edge, both sides. A very intricate section for these. A fighting knife and nor a work knife. Original suspension ring. Archaeological water find condition. As sailors were universally prohibited and prevented from owning pointed knives, the pirate attribution may be applied with confidence. Purchased from a Fort Myers Florida dive and salvage shop in the 1980s. Exceptional preservation.
