John Hunter's Surgical Sutures

Origin
John Hunter FRS (13 February 1728 – 16 October 1793) was a Scottish surgeon, one of the most distinguished scientists and surgeons of his day. He was an early advocate of careful observation and scientific method in medicine. He was a teacher of, friend of, and collaborator with, Edward Jenner, the inventor of the smallpox vaccine. His wife, Anne Hunter (née Home), was a minor poet, some of whose poems were set to music by Joseph Haydn.

This set of sutures once were used by John and became imbued with body healing abilities.

Effects
When used to stitch open wounds or detached limbs or appendages, the sutures will instantly heal the wound. Unfortunately, the sutures will make the user's bones weaker.
