Wikipedia
A candle snuffer is an instrument used to extinguish burning candles. This may be either a (candle)snuffer (a scissor-like device with two flat blades) or an extinguisher (a small cone at the end of a handle). The term 'candlesnuffer' or 'snuffer' is also sometimes used to describe what was formerly known as an extinguisher.
The scissor-like tool could be used to trim the wick of a candle. With skill, this could be done without extinguishing the flame. A small receptacle catches the trimmed bit of wick. This tool was rendered obsolete by the invention of self-snuffing wicks, which curl out of the flame when charred. This allows excess wick to burn away, preventing the wick from becoming too long.
The use of a douter helps to avoid problems associated with blowing hot wax. Extinguishers are still commonly used in homes and churches.
