Dirk

From Karate, Kungfu, Wrestling, Mixed Fighting Information Source

The Dirk was characteristically, almost exclusively, a Scottish dagger weapon. It had a long thin blade, usually sharpened only on one edge, a conical hilt adorned with studs, and often an engraved blade. Dirks were used functionally through the 18th century. From the 19th century on they have been essentially a ceremonial weapon.
