Gunblade

Gunblades were weapons first fielded by the Saronians, best described as rifles with blades protruding below the barrel. Romulan weapons locker technicians made a pair of gunblades out of the souvenir sword Brianna Reiss bought on Saronia for her honeymoon, as well as old disruptor rifles. The souvenir sword's hilt became a tricorder handle. (RIS Bouteina: "Marriage and Honeymoon")
