Dirk
thrusting dagger
A dirk is a long-bladed thrusting dagger. Historically, it gained its name from the Highland dirk (Scottish Gaelic biodag) where it was a personal weapon of officers engaged in naval hand-to-hand combat during the Age of Sail as well as the personal sidearm of Highlanders. It was also the traditional sidearm of the Highland Clansman and later used by the officers, pipers, and drummers of Scottish Highland regiments around 1725 to 1800 and by Japanese naval officers.
Etymology
The term is associated with Scotland in the Early Modern Era, being attested from about 1600. The term was spelled dork or dirk during the 17th century, presumed related to the Danish, Dutch and Swedish dolk, and the German dolch, tolch; from a West Slavic Tillich. The exact etymology is unclear. The modern spelling dirk is probably due to Samuel Johnson's 1755 Dictionary. The term is also used for "dagger" generically, especially in the context of prehistoric daggers such as the Oxborough dirk.
Highland dirk
The Scottish dirk (also "Highland dirk", Scottish Gaelic: biodag), as a symbolic traditional and ceremonial weapon of the Highland Cathairean (cateran or warrior), is worn by officers, pipers and drummers of Scottish Highland regiments. The development of the Scottish dirk as a weapon is unrelated to that of the naval dirk; it is a modern continuation of the 16th-century ballock or rondel dagger.
