- This article is about the Romulan weapon type. You may be looking for the Tessma honor blade or the TOS - Rihannsu novel Honor Blade.
The Honor blade (Romulan: dathe'anofv-sen) is a traditional weapon carried by Romulans. Honor blades are passed down through Romulan families, and are ritually sharpened.
Admiral Valdore i'Kaleh tr'Ihaimehn carried an honor blade with him. He used his honor blade to kill his technologist Nijil after discovering his connection to the Ejhoi Ormiin dissident group. Valdore also used it against Admiral Dagarth when she used a mutagenic device against Haakona Prime without his authorization.
After the ending of the Earth-Romulan War Commander Terix Val'Danadex Trel tr'Llweii used his ritually sharpened blade to behead First Consul T'Leikha after she assassinated Admiral Valdore. (ENT novel: To Brave the Storm)
