The main problem with an axe handle of that length, you have no control over where it lands. Sure, it'll hit with force. But all that force is meaningless if you can't even hit the log in the first place. That's why people use two hands; as the axe head descends and the other hand moves up the shaft, it provides a guide for the head to land exactly where the user wants it to.
