Snuffers are generally associated with candlesticks, but can be used on lamps too. They are shaped like a pair of scissors but have a box on top that collects the carbon residue on the end of the wick. This carbon build-up is called “snuff”, hence the name. They can be used to extinquish or “snuff out” the flame too, and are sometimes associated with this function as well.
Snuffers are typically found made of cast iron but they were also made out of brass or found with silver plating. Some were fitted with an upright holder or a table top tray to rest on.
