I would divert those customers to a whitesmith or a blacksmith with no sense of humour, also, I think if a hammer that person works is 100 years old or more then I would assume that it has been given fair treatment, call me an old (@!#!*$) stick in the mud and theres older ones round here, but respect from any perspective is the way forward. Love the ones your with! Treat yourself and your hammer fair.
