Broad Axe

A broadaxe is a large broad-headed axe. There are two categories of cutting edge on broadaxes, both are used for shaping logs into beams by hewing. On one type, one side is flat, and the other side beveled, a basilled edge, also called a side axe, single bevel, or chisle-edged axe. On the other type, both sides are beveled, sometimes called a double bevel axe, which produces a scalloped cut. (Wikipedia)
