A 'Coming of Age' ceremony whereby the participant, on the eve of their 21st birthday, willing engages in the physical destruction or 'crushing' of a sea shell with the aid of a consecrated sledgehammer. Though the ceremony is believed to have ancient origins, it is widely regarded today as milestone or transition in the participant's life as they cease their old ways and embrace a new life of profound knowledge and wisdom.
