Viking battle axe
A battle axe (also battle-axe, battle ax, or battle-ax) is an axe specifically designed for combat. Battle axes were specialized versions of utility axes. Many were suitable for use in one hand, while others were larger and were deployed two-handed.
Axes designed for warfare ranged in weight from just over 0.5 to 3 kg (1 to 7 lb), and in length from just over 30 cm (1 ft) to upwards of 150 cm (5 ft), as in the case of the Danish axe or the sparth axe. Cleaving weapons longer than 150 cm would arguably fall into the category of polearms.
