Golden Trephine

Detail of a trephine. A knife of sorts used by the Inca of Peru for creating holes in the skull for various medical and religious reasons. This one was a souvenir from the 1984 worlds fair in New Orleans. The gold plated object was from the Peruvian booth. The sparks were created with a Dremel tool which could also be used as a trephine in a pinch,
