Over its long history the Egyptians employed a wide variety of ancient weapons. During the earliest periods stone and wood weapons were used, these early Egyptian weapons included slings, clubs, throwing sticks, stone maces and stone tipped spears. Horn and wooden bows were also constructed and used with stone tipped arrows.
By 4000 BC the Egyptians had started importing obsidian from the Eastern Red Sea areas for their weapons. This glass like stone has properties that allow it to have a sharper point than the sharpest metals; these almost molecularly thin blades are used even today for scalpels.
By the time upper and lower Egypt were first united and their society coalesced around 3150 BC, the Egyptians had already been using bronze weapons. They used bronze for spearheads, axes and maces. It was also during this period that the composite bow came into use, made with horn and wood. Over the following centuries as the Pharaoh's dominated ancient Egyptian society they began to standardize weapons, stock pile arsenals and borrow weapons systems from invading peoples.
