The traditional Scottish dirk is a probable development from the 16th century but like all medieval societies, the Highlander needed a knife for everyday use. The dirk became symbolic of a Highland man’s honour and oaths were sworn on the steel which was believed to be holy. 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.
