Restoration of 500+ summer blacksmith mites

For at least five hundred years, these blacksmith mites were not in the hands of a blacksmith. They were presented to me and scissors from the video (one treasure) by archaeologists, dating from 500 to 900 years according to the depth of tingling, metal oxides and material. I do not need them as a tool. But I felt sorry for them and I decided to restore them to their working condition, for my collection of forging tools.
