Bichawa

The bichawa, also bichwa or bich'hwa (Hindi: बिछवा "scorpion") is an Indian dagger with a loop hilt and a narrow undulating blade, named for its resemblance to a scorpion's sting.

It can be combined with the bagh nakh to form a composite weapon, such as the weapon used by the Maratha emperor Chhatrapati Shivaji Maharaj in combat against Afzal Khan in the Battle of Pratapgarh (1659).
