A Sgian Dubh (pronounced ski-an doo) is a ceremonial knife with a fixed blade, typically worn with full Scottish highland dress. But has been seen worn with other highland attire. Its cutting edge is generally under three inches (7.6cm) and they come in many different designs.
The word Sgian Dubh is Gaelic, and originates from “Sgian” meaning knife or dagger, and “Dubh'' meaning black. The use of the Gaelic ‘black’ is thought to come from the use of the original black bogwood used for the hilt of the knife. Hundreds of years ago it was secreted away on oneself, it was also referred to as a dark weapon - hidden against the Highland custom of guests depositing weapons at the house door before entering. These blades were once hidden in a pocket under the armpit, but it has become customary to position the sgian dubh more openly as a courtesy. As early as the 1800s it was seen worn tucked into the top of socks in paintings, with a few inches of the handle showing. It was also a great tool to cut meat & fruit. Traditionally it is worn in the right sock with the handle showing, though strictly speaking a left-hander could wear it on the left.
