These obsidian arrowheads have been shaped by hand in a process known as ‘knapping’ into the form of ancient Native American artifacts. Because they are hand made, each one is different in shape and size with considerable variation in style. They are made from real natural obsidian glass, one of the same materials that was originally used by native populations. Obsidian is nature’s natural glass that comes from volcanic uprisings and is sharp and shatter prone similar to regular glass. These obsidian points are much sharper than my agate and crystal arrowheads. Since these are reproductions, they are not subject to antiquities laws and so are entirely legal to own, buy, and ship in all US states. Photos are stock photos, you will not receive these exact arrowheads but ones very similar.
