Technical Observations: The patina is dark brown with patches of raised green corrosion and spots of underlying red. Large areas of bright metal are visible. The rough line of the sharpened edge is the result of losses due to corrosion. There are also losses to the top end of the tang. Long, crude scratches and chatter marks throughout are the result of mechanical cleaning.
The blade was probably cast and then refined and hardened by hammering. Although the object’s surface was damaged by cleaning, the refined shape indicates the surface was probably finely finished. The hole in the tang is poorly preserved, and it is not clear if it was drilled or punched.
