Guitar pick

A guitar pick (American English) is a plectrum used for guitars. Picks are generally made of one uniform material, such as some kind of plastic (nylon, Delrin, celluloid), rubber, felt, tortoiseshell, wood, metal, glass, tagua, thermosetting plastic or stone. They are often shaped in an acute isosceles triangle with the two equal corners rounded and the third corner less rounded. They are used to strum chords or to sound individual notes on a guitar.

In British English, guitar picks are referred to as plectra, reserving the term pick to identify the difference between this and finger picks.
