Bladed Scepter

The Bladed Scepter was a rare scepter sold in Egypt during the 1st century BCE whose decorative ball at the end held a steel blade. The blade, thin and inserted deeply into the ball, was fairly hidden to the mild observer, such that the real lethality of the weapon could come as a surprise to enemies. The pole itself was ornately carved with artistic patterns, and the oval ball was painted in the manner typical of totem poles. While not the deadliest of weapons, the scepter could be favored for its lightness and long reach coupled with its inconspicuous blade.
