Tools naturally evolved over time, so those used around 10,500 years ago were not the same as those used in 300 AD; trade with white Europeans after about 1600 provided native groups with metal tools that had previously been unobtainable.
Prehistoric tools included fluted and pressure-flaked stone spear points, scrapers, knives, twist drills, fishing plummets, "ulu" knives, hide scrapers, gouges and other tools. Bone was used to make awls, stoneworking tools and arrow points. Atlatl weights, fishhooks, harpoons, axes, farming hoes, weapons and berry mashers were all made from stone.
