Klingon concertina
From Memory Alpha, the free Star Trek reference.
The Klingon concertina is a small, handheld Klingon musical instrument.
The Klingon chef aboard Deep Space 9 owned one of these instruments and often used it to entertain his customers. (DS9: "Playing God")
- The book The Making of Deep Space Nine revealed, that in typical Klingon fashion, this concertina could also be used as a weapon.
