prohibited in 1747 those Gael who could not read or sign an oath were required to swear a verbal oath, "in the Irish (Scots Gaelic) tongue and upon the holy iron of their dirks", not to possess any gun, sword, or pistol, or to use tartan: "... and if I do so may I be cursed in my undertakings, family and property, may I be killed in battle as a coward, and lie without burial in a strange land, far from the graves of my forefathers and kindred; may all this come across me if I break my oath." During the period of proscription, only service in a British regiment permitted Highlanders to bear their traditional arms and dress. The 78th Fraser Highlanders, raised in 1757, wore full highland dress uniform; their equipment was described by Major-General James Stewart in 1780 as including a "musket and broadsword, to which many soldiers added the dirk at their own expense." As is well documented in the oral traditions and in almost every title written prior to 1979; The perceived "holiness" of the steel is likely to have originated in folk superstitions. These origins are often ascribed to "magic" in the forging of Germanic steel. For this reason, it is established that Highlanders retained reverence for blades forged from Solingen steel. The modern development of the Scottish dirk into a ceremonial weapon occurred during the 19th century. The shape of the grip developed from the historical more cylindrical form to a shape intended to represent the thistle. Fancier fittings, often of silver, became popular shortly after 1800. The hilts of modern Scottish dirks are often carved from dark colored wood such as bog oak or ebony. Hilts and scabbards are often lavishly decorated with silver mounts and have pommels set with cairngorm stones. The blades measure 12" in length and are single edged with decorative file work known as "jimping" on the unsharpened back edge of the blade. When worn, the dirk normally hangs by a leather strap known as a "frog" from a dirk belt, which is a wide leather belt having a large, usually ornate buckle, that is worn around the waist with a kilt. Many Scottish dirks carry a smaller knife and fork which fit into compartments on the front of the sheath, and a smaller knife known as a sgian dubh is also worn tucked into the top of
