Question: how much do axes weigh?
Answer: 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.
