Flat grey metal blade with slots on pale background
A single flat, grey metal piece with a tapered, curved outline and a pointed tip sits against a pale grey backdrop, casting a soft shadow. Two small rectangular slots pierce its upper and lower edges, and a faint stamped mark appears near the middle. No figures, printed colour, or chart layout are visible.
