Sgian Dubhs

The Sgian Dubh (pronounced "skee(a)n doo", IPA /skian dubh, or lightly diphthongised /skiən/)
is a ceremonial dagger (Gaelic sgian) worn as part of the modern Scottish Highland dress along
with the kilt. It is worn tucked into the hose with only the pommel visible.
The name comes from the Gaelic meaning "black knife", where "black" may refer to the usual
colour of the handle of the knife. It is also suggested that "black" means secret, or hidden, as
in the word blackmail. This is based on the stories and theories surrounding the knife's origin.
