A Pickaxe is a hand tool featuring a long, curved, tapered head, with each end being either a point, chisel, or blunt-faced. It is a common implement for working the earth.
In wartime, a soldier may use a pickaxe to dig foxholes in hard earth, or loosen material to fill gabions. Its weight and slender tip also make it effective at piercing thin armor, and so may be used as a weapon.
