Technical Observations: Most of the surface is covered with white, chalky accretions. At the edges, where the accretions have chipped off, the patina is a dark brown. Very small areas of green, red, and some bright metal are visible. The rough line of the sharpened edge is the result of losses from corrosion. There is no evidence that the piece has been cleaned.
The blade was probably cast and then refined and hardened by hammering. The area surrounding the hole in the tang is concave on one side and slightly convex on the other, which may indicate that it was punched.
