The term refers to a specific type of knife, typically a small dagger, historically carried by Scots Highlanders. It was often concealed in the armpit or inside the stocking (sock), and formed a part of traditional Highland dress. Examples can range from utilitarian working tools to ornate, decorative weapons reflecting the status of the owner.
The significance of this edged weapon extends beyond simple utility. It served as a symbol of personal readiness and self-reliance, reflecting a cultural emphasis on individual defense and the potential for conflict. Historically, bearing it was a customary practice, rooted in the Highland clan system and the often-turbulent environment. The ornamental versions demonstrate craftsmanship and symbolize social standing.
