Tusks and fangs
The tusk represents human strength, and the ancestral connection with the animal's spirits, those who the humans, in the cradle of civilization, had to face to survive. The tusk of the defeated animal was worn, so its spirit was now at the service of the man. Carrying it in the neck symbolizes the ability to overcome adversaries, and the men's power to prevail in any situation. It's believed that it makes the inner strength arise, that connects us with elder powers and makes us invincible. It also increases the sexual appeal.
