A bearded axe, or Skeggöx (from Old Norse Skegg, beard + öx, axe) refers to various axes, used as a tool and weapon, as early as the 6th century AD. It is most commonly associated with Viking Age Scandinavians.
The bearded axe in particular was a popular style. This weapon, named because the lower part of the head is flat instead of pointed, was a particularly devastating style due to fact that the broad, thin edge was backed by a thick body for resiliency. Such a weapon could strike hard against a man in armour, or compromise a shield with its sheer force.
