Feature: Horn-handle knife Jambiya symbolizes Yemeni tribes' peace

Horn-handle knives are seen at a store in Sanaa, capital of Yemen, June 26, 2019. The Yemenis have not been affected by the Western stylish changes as they still proudly keep their ancestors' traditional dress, especially the wear of the horn-handle knife for nearly 3,000 years.
