This is a bronze dagger from the Dong Son culture in ancient Southeast Asia. It measures roughly 263 mm and weighs 144 grams. It has a spectacular cuprite crystal patina on one side that I could not capture in the photos. There are also the remnants of a wood scabbard in the patina that should be visible in the photos.This piece has stable metal with a sculpted round handle and slender triangular blade. There are no signs of repair to this wonderful dagger.
