sgian

A sgian, also known as a sgian-dubh, is a small, single-edged knife traditionally carried in the top of the sock or stocking, with the hilt protruding. It is a part of Scottish Highland dress. The name is derived from the Gaelic words "sgian" meaning knife and "dubh" meaning black, possibly referring to the black wooden or bone hilt, or to the fact that it was a concealed weapon.

Historically, the sgian-dubh was a common personal weapon, though its practical use diminished over time. It became more of a ceremonial or decorative item associated with Highland attire. The knife typically has a blade of around 3 to 4 inches, often made of steel. The hilt can be made from various materials, including wood, bone, or even horn, and is frequently decorated with Celtic knotwork or other traditional patterns. Some hilts may feature a small stone, such as a Cairngorm or jet, set into the pommel.

While once a symbol of status and a means of defense, the sgian-dubh is now primarily worn as an accessory to the kilt, particularly for formal occasions such as weddings or Highland games. It is considered an integral part of the complete Highland outfit, alongside the kilt, sporran, and tartan. Its presence signifies a connection to Scottish heritage and tradition.
