Tongs are metal pincers you grip hot food with instead of your fingers. A pair of tongs, kitchen tongs, salad tongs.
They are a plural-only noun like scissors and trousers, so it is a pair of tongs and never a tong. A blacksmith's tongs hold iron in the fire, and curling tongs heat hair. The two arms work as a lever, which is why tongs grip harder than fingers can.
