Arrowhead is a tip, usually sharpened, added to an arrow to make it more deadly or to fulfill some special purpose. The earliest arrowheads were made of stone and of organic materials; as human civilization progressed other materials were used. In the Stone Age, people used sharpened bone, flintknapped stones, flakes, and chips of rock as weapons and tools.

Arrowheads can be made from flint, chert, obsidian, jasper, quartzite, and other types of stones that are brittle and have fine grained. An Apache made four stone points and it only took him six a and half minutes to make all four of them. How the Native Indians made arrow heads. To make an arrow head point the first step is to hammer flint with a hammerstone to remove any large sharp flakes of the stone. The next was called pressure flaking which is made by placing a pointed tool, such as an antler horn on the edge of the stone while applying inward pressure to the tool so as to remove any small thin flakes from the stone. Notching was the last step which was made by using pressure flaking and grinding the stone, to carve out any gaps. This allowed it to be bound to the arrow shaft.
