The sgian-dubh is a small, singled-edged knife worn as part of traditional Scottish Highland outfit. It is worn tucked into the top of the hose with only the upper portion of the hilt visible. The sgian-dubh is normally worn on the right leg, but can also be worn on the left, depending on whether the wearer is right or left-handed.
The kilt pin is a piece of jewellery that is usually worn on the lower corner of the outer apron of a kilt. Its function is to prevent the apron blowing open, by adding weight. It should never be pinned through both aprons, since this would result in distorting the proper hang and action of the kilt and at worst could result in tearing the kilt.
