A small knife called a sgian-dubh is often worn tucked into the top of the kilt hose which is commonly worn with the kilt. This item has its historical origins as a utility knife. Again, as with most items of traditional Scottish apparel and accessories, they come in a very wide variety, from fairly plain to quite elaborate silver and gem ornamented designs. A longer knife, called a dirk is sometimes worn hung from the kilt belt.
On the front apron of a kilt, near the selvedge and the open, fringed part of the apron, you will often see a kilt pin, often topped with a small decorative clan crest or other similar design. Typically, the rule for the placement of the kilt pin is such that it must be two pattern squares over and up from the edge of the kilt fabric.
Two styles of kilt pins can be seen in the accompanying photo. (Note the kilt damage resulting from using the thick-shanked version, however.) This is a decorative item meant to be pinned through the outer apron only. It is not heavy enough to prevent the kilt apron from blowing open in a breeze. 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. Of course, Highland dancers do not wear the pin through both aprons (when they wear one at all) since the action of the kilt is an essential part of the dance.
Often, a clan crest badge will be pinned to the left side of the Balmoral or Glengarry.
