Jambiya

Janbiya, also spelled janbia, jambiya, and jambia, (Arabic: جنبية‎ janbīyah), is the Arabic term for dagger, but it is generally used to describe a specific type of dagger with a short curved blade that is worn on a belt. Although the term jambiya is also used in other Arab countries, it is mostly associated with people of Yemen. Men typically above the age of 14 wear it as an accessory to their clothing.
