Technical Observations: The patina has been stripped down to a brown and black metallic surface with some pale green corrosion. The surface is etched and pitted. The blade has suffered some loss to the cutting edge, where there are several stress cracks.
The knife blade was made by casting and hot working. Under the microscope, dendrites from casting show deformation from hammering. The three holes for attachment to a handle were made by punching and turning in order to receive a rivet-type mechanical attachment that is no longer present.
