Tongs

Pass the tongs and the facts.

  • Tongs are tools used to handle items, and generally move the item from one place to another, or turn things, like a piece of meat on a barbecue.

  • Tongs are used mainly for handling food or hot items.
  • Modern tongs are usually made from plastic, metal, stainless steel, or other material, depending on their purpose.

  • Tongs are used to extend the hand or as a replacement handler for potentially dangerous items.
  • Tongs usually have a sprung end so that the operator is required to squeeze the middle of the tongs to grab hold of an item, or they have a pivot which requires the user to squeeze the handles at the end to grip onto items, these being more effective at holding heavy items due to the extra force able to be applied.
  • There are many types of tongs including barbecue tongs, salad tongs, blacksmith tongs, crucible tongs, ice cube tongs, sugar cube tongs and fire tongs.
  • Tongs are often called ‘a pair of tongs’ and the word comes from the Old English, ‘tange’ or ‘tang’, meaning ‘that which bites’.
  • There is evidence of Egyptians using metal rods and tong like tools to hold objects over fire, in around 1450 BC.
