Claim 0:
1. A shovel, comprising:
a shovel blade;
a handle assembly having a lower handle section configured to slidably and concentrically receive an upper handle section, the lower handle section comprising a hollow tube having an impact portion at a distal end, wherein the distal end is attached to the shovel blade, and wherein, when the upper handle section moves axially within the lower handle section, it functions as an impact hammer;
a hand grip disposed at a proximal end of the upper handle section; and
a locking assembly for locking the upper handle section in one of an extended position and a compressed position relative to the lower handle section, the locking assembly comprising a spring-biased collar disposed at a proximal end of the lower handle section, wherein the spring-biased collar prevents relative axial movement between the upper and lower handle sections by pressing a plurality of ball bearings into an annular channel disposed around the upper handle section, wherein releasing the locking assembly allows the upper handle section to slide within the lower handle section.
