Sgian Dubh: Worn in right hose top (Pronounced "Skeen Doo")

The origins of the name Sgian Dubh (Gaelic for Black Knife) are thought to have emerged from this knife's dark appearance - the early handles were often made from dark bog wood and the blade would become dark through use and age.

A second theory is that it originated from the dark or sinister nature of an easily concealed weapon - which is why it has become traditional to keep the Sgian Dubh in open view in the top of the stocking whilst wearing Highland Dress to show that its wearer is amongst friends and has no ill intent.
