A shovel includes a handle assembly being pivotally connected to a blade or a bracket of a blade for pivoting between a first position or second position at a first or second acute angle between the blade axis and the handle axis. The blade also has a third position at substantially a right angle between the handle axis and the blade axis. A pair of braces are attached to the blade. A plurality of holes are provided at the upper end of the pair of braces, wherein one hole of the first cross brace is aligned with one hole of the second cross brace for establishing each of the first, second, and third positions of the blade.
