The sgian-dubh is a traditional Scottish knife, typically worn as part of Highland dress. It is usually tucked into the top of a kilt hose or sock, making it both a practical tool and a decorative accessory. The blade is often around 3 to 4 inches long and can be made from various materials, including stainless steel and damascus steel. Historically, the sgian-dubh served as a utility knife for everyday tasks, but it also held cultural significance. The name translates to "black knife" in Scottish Gaelic, and it is often adorned with intricate designs. Today, it is commonly worn during formal occasions, such as weddings and Highland games.
