1. A shovel having a fulcrum projection, the shovel comprising: a digging blade having a proximal end, a distal end, a substantially concave front, a substantially convex back, and two edges;a handle attached to the proximal end of the blade; anda fulcrum member located at the back of the blade, the fulcrum member comprising (i) a first bar having a proximal end at the back of the blade and a distal end, the first bar forming an angle with the handle of approximately 45 degrees, and (ii) a second bar that is substantially parallel to the handle, the second bar having a plurality of holes;a bracket in which the second bar is inserted, the bracket fixed near the proximal end of the blade, the bracket having a pin that may be removably inserted into one of the plurality of holes; andat least one footrest near the proximal end of the blade. 2. A shovel according to claim 1, wherein the edges of the blade are serrated. 3. A shovel according to claim 1, wherein the edges of the blade are sharp. 4. A shovel according to claim 1, wherein the fulcrum member is substantially perpendicular to an axis that that is substantially orthogonal to the handle and that intersects the blade halfway between the two edges. 5. A shovel according to claim 1, wherein the fulcrum member is located between the distal end and the proximal end of the blade. 6. A shovel according to claim 1 wherein a portion of the fulcrum member near to the distal end of the fulcrum member curves in a convex direction with respect to the handle. 7. A shovel according to claim 1, wherein the position of the fulcrum member between the proximal and distal ends of the blade is slideably adjustable. 8. A shovel according to claim 7, wherein the position of the fulcrum member may be adjusted only in a direction parallel to the handle. 9. A method for digging with shovel having a fulcrum projection, the method comprising: providing a shovel as provided in claim 1;inserting the blade of the shovel into the ground so that part of the fulcrum member rests upon the ground; androtating the handle downward around the fulcrum member such that the blade rotates upward toward a horizontal position.
