A blacksmith or metalworker who specializes in making or repairing chains.
From English 'chain' + 'smith' (from Old English 'smið', meaning metalworker). A direct parallel to 'goldsmith' or 'blacksmith', formed in the medieval period.
Chainsmiths were medieval specialists who could make chains strong enough to hold castles' gates but also delicate enough for jewelry—their skill bridged war and beauty.
