The double headed axe dates to the late stone age, obviously it changed because the more people used it, the more new ideas came into making it better. The handle material changed and also did the blade itself once they figured what was more effective.
The current double headed axe material is mostly made with a steel blade which is much more powerful compared to when they used wood also the grip of the axe changed so it's harder for it to slip.
