Bachi (桴, 枹) (also batchi) is the name for the straight, wooden sticks used to play Japanese taiko drums, and also (written 撥) the plectrum for stringed instruments such as the shamisen and biwa.
Bachi used for stringed instruments are actually picks. They are very distinct in form and use from Western-style picks, which are usually smaller in order to be held between or mounted to fingers. In shape, bachi are similar to an ice scraper or a putty knife.
