Antique Hammer

Description

Antique Hammer Surgical Planishing Jeweler.  Unique old hammer.  Please let me know if you know the specific use for this hammer.  Cannot tell what the handle is made of - wood? but no visible grain.  7 1/4" X 1 7/8".  Handle does have a small crack on each side at the neck - see picture.  The hammer could have been abused, I don't think the head would have been pitted when purchased initially.  See pictures and ask any questions.
