A leather workerís cast lead palm guard. One surface is flat and the other is convex with a central circular indentation. The guard would have been wrapped in cloth or held in a pouch, and used to force needles through the tough material, while protecting the userís palm. The indentation would prevent the needle from glancing off the surface. The shape of the guard suggests that it may have been cast in a mould made with an oyster-shell.

The recorder notes that "Needle marks can be seen close to the central circular indentation."
