This is a military issue dagger in the shape of an old Ottoman Jambiya from the 16 century. (The original one is in the Topkapi palace museum). For more details on this military issuem please see: Military issue Turkish Dagger . The blade is 8 ¼ ” heavy, curved and double edged. It has the ‘Tughra’ (the royal stamp) of Muhammad V, the moon and star symbol of the Turkish army, a date 1334 (1915) and a serial number 2520. On the other side of the blade is a long quote from the Koran. The hilt and scabbard are brass chased in the style of the original dagger with the same serial number stamped on the belt loop. Very good condition. The engraved inscriptions are very slightly worn and the belt loop was re-soldered long ago. Certainly an unusual addition to a collection of edged weapons, be it a collection of Turkish / Islamic blades or of military blades.
