Abstract: Foldable axes cut wood while being safely and easily transportable. The foldable ax provides the benefits of a long handled ax by consisting of four handle elements attached to a blade which unfold and lock in the in use position. The handle elements enclose the blade in the storage and transport position, thereby preventing the cutting edge of the blade from coming into contact with objects it could damage and rendering the foldable ax much more compact. A series of latching mechanisms removably secure each handle element in place in the in use position. The handle elements are hingedly attached to one another.
