I must admit, I am significantly less familiar with the short unbalanced weapons than I am with, say, the sword and spear. Additionally, there are no period texts detailing the use of the mace or the short axe. Dagger, sword, spear, poleaxe, yes - axe and mace, no. So much of what we can say about these weapons is speculative.
What we can do is look at surviving specimens and accurate reproductions to get a sense of what the weapons were like, physically.

First off, these weapons are shorter than I had previously thought - one handed maces don't seem to vary much from the 24" mark. They're also lighter than I had thought - rarely more than 3 lbs, and often only 2 lbs - sometimes less. The same goes for axes, although they tend to be a little smaller and lighter still!
The balance point ranges from the middle of the weapon to a little past the middle (i.e. closer to the head). It looks like the balance point would be further, but there you are.
This all contributes to making maces and axes significantly handier in combat than you might expect.
Mace - Description
The difference between a mace and a club is subtle. To my mind, the defining features of the mace are two-fold: all-metal construction, and the use of flanges or knobs on the head.
Balance point: 2/3 up from butt end.
Mace Variation - Morning Star
The morning star is simply a mace with spikes instead of knobs or flanges, especially if there is one larger spike at the very top for thrusting.
Military axes had very small, thin, light heads compared to woodcutting axes or hatchets. The head would also often have a cut-out between the blade and haft, allowing for the axe to be used for hooking, and reducing weight while maximizing cutting area.
Axe Variation - Military Pick / Warhammer
A military pick or warhammer are basically just piercing or bludgeoning versions of the axe. Some axes even incorporate a pick on their back end, and most warhammers have a hammer side and a pick side. Otherwise, they are very similar to an axe.
It seems to be a common misconception that maces and axes were big, heavy things that dealt damage through their weight and brute force. The reality is that they were usually smaller and lighter than swords, and relied as much on the speed of the swing as on their unbalanced weight distribution.
Archaeological evidence shows that people killed by axe blows were typically struck from above, leading me to believe that fendente (i.e. overhead strikes) were more typically used with these weapons than mezzane (strikes parallel with the ground). Logically, this makes sense - gravity would be pulling the heavy head of the weapon down, lending more force to the blow for free.
The other common injury with axes seen is leg injuries. This is likely because axes were used with shields - two fighters with shields apparently find opportunities to hook the axe under the opponent's shield. Later treatises of the sword don't describe leg strikes - they focus on attacks to the head, neck, and weapon arm.

If using an axe or mace with your other hand empty, you could possibly do some dagger/baton defences with the shaft. The problem immediately apparent in adapting these plays is that axes - while they can thrust - are not suited for the devastating thrusts to the vitals that daggers are capable of.
It may be possible to do some of the sword defences, but the short shaft and lack of guard would limit your options there. While handier than you'd think, an axe or mace is not going to be a great option for your only defensive weapon.
Except in urgent situations, typically an axe or mace would be used with a shield. This makes up for the lack of agility compared with a sword - at least compared to a sword without a shield.
