Why did they use buffalo bones for toys needles and tools?

Buffalo bones were used for toys, needles, and tools primarily because of their durability and availability in regions where buffalo roamed. The bones could be easily shaped and sharpened, making them suitable for various practical applications, including sewing and crafting. Additionally, utilizing all parts of the buffalo was a sustainable practice that reflected the resourcefulness of indigenous cultures in North America. This practice also minimized waste, as every part of the animal was repurposed for different uses.
