Bichuwa
The bichuwa or bichawa (pl. bichuwe) (Hindi: बिछुवा, Urdu: بچھوا) is a dagger, originating from the Indian subcontinent,  with a loop hilt and a narrow undulating sharp blade. It is named for its resemblance to the sting of a scorpion, for which the Hindi name is bichuwa. The weapon was based on the maduvu, or horn dagger created in South India, and many bichuwa have blades which retain the shape of buffalo horns. Early examples of the bichuwa come from the medieval southern  Karnataka empire of Vijayanagara.
