Horseman's Mace
The first horseman's maces were a wooden handle, about 18 inches long, with a leather wrist strap at the bottom of the handle so the weapon would not be dropped, and a metal head.
As time progressed, knights preferred to have maces made entirely of metal. The horseman's mace became an important weapon to the knight.
Knights usually keep a mace slung over a hook on the saddlebow. Not surprisingly, an alternate name for the horseman's mace is the knight's mace.
This type of mace is a one-handed weapon.
