Pardon Me For Asking

[Birchy]

Where does Belcher Chain come from? Were these things named after their inventor?

[Quizmonster]

It was possibly named after an early 19th century boxer of that name. Click http://www.24carat.co.uk/belcherdefinition.html for a web-page created by someone who wanted to find the answer to the very same question as you, Birchy, and went to considerable lengths to do so.

All I know is that a link in a belcher (neck) chain is stronger than other types of links!
