Club

A club is a blunt weapon used to cause percussive or bludgeon damage. Essentially cylindrical, a club may be made of any substance, although materials with more density will cause more damage to the target and will survive more uses. Swung one- or two-handed, the club is the earliest of weapons, and is still in widespread use today.
Add a metal head to it (or replace the top section with metal) and you then move into the mace.
