A tool according to claim 1; wherein the support wall is positioned approximately midway between the rear and front walls of the head. 3. A tool according to claim 1; wherein the rear wall, the front wall and the support wall are generally parallel to one another. 4. A tool according to claim 1; wherein the rear wall has an opening through which the handle extends for connection of the base end portion of the handle to the support wall of the head. 5. A tool according to claim 1; wherein upper edges of the side walls are sloped from the rear wall downwardly towards the front wall. 6. A tool according to claim 1; further comprising means for preventing relative movement between the fulcrum member and the head. 7. A tool according to claim 6; wherein the means for preventing relative movement comprises a pair of depressible protrusions mounted on the fulcrum member for engagement with the respective side walls. 8. A tool according to claim 1; further comprising means for adjusting the position of the fulcrum member to preselected positions relative to the head in the direction transverse to the handle. 9. A tool according to claim 8; wherein the means for adjusting comprises the pair of aligned openings that permit movement of the fulcrum member relative to the head in the direction transverse to the handle and a pair of depressible protrusions mounted on the fulcrum member for engagement with the side walls of the head to removably connect the fulcrum member to the head at any one of the preselected positions. 10. A tool according to claim 1; wherein the head is formed of sheet metal. 11. A tool according to claim 1; wherein the handle comprises an elongated tubular member; and further comprising a weight body disposed in the tubular member at a regions thereof including a portion of the tubular member extending through the opening of the rear wall of the head and the free end portion position of the tubular member connected to the support wall. 12. A tool according to claim 1; wherein the handle is tubular in construction; wherein the fulcrum member has a pair of depressible protrusions for engagement with the side walls of the head to removably connect the fulcrum member to the head at any one of preselected positions relative to the head in the direction transverse to the handle; and wherein the means for storing comprises a bore of the tubular handle having an inner diameter greater than an outer diameter of the fulcrum member for receiving therein the fulcrum member, the handle having a hole communicating an exterior surface of the tubular handle with the bore thereof such that when the fulcrum member is inserted into the bore of the tubular handle, one of the pair of depressible protrusions of the fulcrum member engages the hole of the tubular handle to removably retain and store the fulcrum member in the bore of the tubular handle. 13. A tool according to claim 1; wherein the wedge-shaped head has a top end and a bottom end opposite the top end; and wherein the bottom end is closed by the bottom wall from which the lateral side walls, rear wall, and front wall extend to form the wedge-shaped head as an open box structure that is open at the top end. 14. A tool for removing sheathing and decking material, the tool comprising: a head having a front end, a rear end, a top end and a bottom end opposite the top end, the bottom end being closed by a bottom wall having a plurality of side walls defining an open, generally wedge-shaped box structure that is open at the top end, the plurality of side walls including a pair of opposite lateral side walls connected to and extending from opposite edges of the bottom wall, a rear wall disposed at the rear end and connected to the bottom wall and the side walls, and a front wall disposed at the front end and connected to and extending between the bottom wall and the side to provide an interior space defined by the bottom, side, rear and front walls, upper edges of the side walls sloping from the rear wall downwardly towards the front wall;a support wall disposed in the interior space of the head and extending between and connected at opposite edges thereof to the side walls of the head;a tubular handle having a bore, a hole communicating an exterior surface of the handle with the bore, a free end portion and a base end portion, the base end portion being integrally connected to the support wall of the head with the handle free end portion projecting rearwardly from the rear end of the head; anda tubular fulcrum member that removably connects to the head proximate the rear end thereof so that the fulcrum member extends in a direction transverse to the handle to provide a fulcrum during operation of the tool, the fulcrum member being configured to be removably received and stored in the bore of the handle during non-use of the tool, and the fulcrum member having at least one depressible protrusion such that when the fulcrum member is stored in the bore of the handle, the depressible protrusion engages the hole of the handle to removably retain the fulcrum member in the bore of the handle. 15. A tool according to claim 14; wherein the support wall is positioned approximately midway between the rear and front walls of the head; and wherein the rear wall, the front wall and the support walls are generally parallel to one another. 16. A tool according to claim 14; wherein the rear wall of the head has an opening through which the handle extends for connection of the base end portion of the handle to the support wall of the head; and wherein the side walls of the head have a pair of aligned openings proximate the rear end of the head for receiving therethrough the fulcrum member. 17. A tool according to claim 14; wherein the at least one depressible protrusion comprises a pair of depressible protrusions. 18. A tool according to claim 17; wherein the pair of depressible protrusions are configured to engage the respective side walls of the head to prevent relative movement between the fulcrum member and the head during operation of the tool. 19. A tool for removing sheathing and decking material, the tool comprising: a head having a rear end, front end, a bottom wall, a pair of opposite lateral side walls connected to and extending from opposite edges of the bottom wall, a rear wall disposed at the rear end and connected to the bottom wall and the side walls, a front wall disposed at the front end and connected to and extending between the bottom wall and the side walls, an interior space defined by the bottom, side, rear and front walls, and a support wall disposed in the interior space and extending between and connected at opposite edges thereof to the side walls, upper edges of the side walls sloping from the rear wall downwardly towards the front wall;a handle having a free end portion and a base end portion, the base end portion being integrally connected to the support wall of the head with the handle free end portion projecting rearwardly from the rear end of the head; anda fulcrum member that removably connects to the head proximate the rear end thereof so that the fulcrum member extends in a direction transverse to the handle to provide a fulcrum during operation of the tool, the fulcrum member having a pair of depressible protrusions for engagement with the respective side walls of the head to prevent relative movement between the fulcrum member and the head during operation of the tool, the depressible protrusions, upon being depressed, allowing the fulcrum member to be displaced in the direction transverse to the handle for positioning the fulcrum member to preselected positions along the transverse direction;wherein each of the handle and the fulcrum member is tubular in construction, the handle having a bore with an inner diameter greater than an outer diameter of the fulcrum member for receiving and storing therein the fulcrum member during non-use of the tool, the handle having a hole communicating an exterior surface of the handle with the bore thereof such that when the fulcrum member is stored in the bore of the handle, one of the pair of depressible protrusions of the fulcrum member engages the hole of the tubular handle to removably retain the fulcrum member in the bore of the handle. 20. A tool according to claim 19; wherein the wedge-shaped head has a top end and a bottom end opposite the top end; and wherein the bottom end is closed by the bottom wall from which the lateral side walls, rear wall, and front wall extend to form the wedge-shaped head as an open box structure that is open at the top end.
