Ancient maces were not limited to Egypt or “Persian” regions. Some were intricately carved which to me suggests they were not necessarily thrown or considered disposable in ancient times. An elaborate one found in the region of Wales is particularly interesting.

For a few hundred $ U.S., one can actually purchase a supposedly “ancient” mace head. These were too numerous to have merely been ceremonial.

I am not vouching for the accuracy of his web site. But, Shawn Caza wrote a pretty good write up on the known history of the mace that seems pretty much on target with what I have been able to find. The pictures of actual medieval period maces are worth looking at to. http://otlichnik.tripod.com/medmace0.html
