I always take the Ivories. Native Americans from Canada and the States use them as jewellery or part of their traditional regalia for ceremonies. It was said that back in the old days anyone could hunt buffalo (way back when they numbered in the hundreds of thousands), even the women and older children helped, but it took a true hunter, what they called a "worthy man" to kill a moose or elk. Thus, “worthy men” would take the ivories, for their own use or as gifts, especial men trying to win the hand of new bride.
The most common use was, and still is to this day, earnings, for men and women. Nothing shouts “provider” more then a man that can feed his family off the land and that’s what the earnings on the most basic, non-spiritual, level represent. There is also a more spiritual reason but I am not the person to articulate that meaning.
Also I could be wrong but I read somewhere that elk are the only North American animals to produce ivory teeth. So keep them and wear them with pride as only a select few men (or women) have the skills and desire necessary to harvest such a noble animal.
Oh yeah, the stick and rock method works best in my experience.
