If you're ever at a dinner party where the host has a set of forks that look like these, you might want to consider leaving, quickly.
These are Fijian "cannibal forks" used for eating human flesh. The iron dance blog
offers this description of them:
The cannibal fork, or iculanibokola, was used by attendants during ritual feasts to feed individuals considered too holy to touch food. These forks arose for several reasons. First is a cultural taboo that prohibits chiefs and priests from touching food with their hands. Common Fijians generally did not use utensils until Europeanization. One of the most important ceremonies a chieftain participated in was the devouring of their or the tribes enemy. Combining the significance of the event and the inability to use their hands the chiefs needed a way to participate-hence the development of the cannibal fork. Forks became a way to show power and influence. The fancier more elaborate the fork, the higher status the owner had.
Fijian cannibal forks are still made, to sell to tourists. What the tourists use them for... I guess that's their own business.
