A shark's tooth implement made from a single shark's tooth attached by plaited fibre to a pierced hole in the end of a piece of ironwood. The wood is tapered at the handle end. Another piece of fibre passes through a hole halfway along the length of the handle, presumably originally to form a wrist strap.

While this has traditionally been described as a dagger, it is more likely to be for scarifying or blood letting. The form and the use of the coconut fibre suggests it may come from Kiribati.

This item is said to have been brought back from James Cook's 3rd voyage, but this provenance seems unlikely. As this piece was also originally classified as a 'dagger' and from Hawaii it may represent one of the many objects that proliferate supposedly connected to Cook's death on Hawaii in 1779, where he was stabbed in the back.
