A pitch adjustable bi-directional shovel includes a substantially flat blade including a forward edge and a rearward edge. Each edge of the blade includes a contact surface. A pivot is secured to the blade. A handle is provided including a first end and a second end, the first end being rotatably mounted to the pivot. An adjustable retention assembly is secured to one or more of the pivot, the blade, or the handle, wherein the pivot and the adjustable retention assembly cooperate to alter the pitch of the blade with respect to the handle so as maintain the blade in general parallel orientation with the associated debris laden surface. The contact surface of the forward edge slideably engages the associated debris laden surface when urged in the forward direction and the contact surface of the rearward edge slideably engages the associated debris laden surface when urged in the rearward direction.

1. A pitch adjustable ash shovel for removing ash debris from an associated ash laden surface, the adjustable ash shovel comprising: a blade comprising a transverse forward edge and a transverse rear edge, the forward and rear edges of the blade comprising respective forward and rear contact surface
1. A pitch adjustable ash shovel for removing ash debris from an associated ash laden surface, the adjustable ash shovel comprising: a blade comprising a transverse forward edge and a transverse rear edge, the forward and rear edges of the blade comprising respective forward and rear contact surfaces for slideably engaging the associated ash laden surface, the blade further comprising a first side wall and a second side wall, wherein the first and second side walls are concave such that that the blade is wider at said forward and rear edges and narrower between said forward and rear edges;a pivot secured to the blade between the forward and rear edges, the pivot comprising an axis of rotation;a handle including a first end and a second end, the first end being rotatably mounted to the pivot for rotation of said handle relative to said blade about said axis of rotation;a retention assembly secured to one or more of the pivot, the blade, or the handle;wherein the pivot and the retention assembly cooperate to alter the pitch of the blade with respect to the handle; and,wherein said handle is selectively movable from a first position in which said retention assembly is engaged with said handle and secures said handle at a select pitch relative to said blade to a second position in which said handle is disengaged from said retention assembly and said pitch of said handle relative to said blade is adjustable by rotational movement of said handle relative to said blade about said axis of rotation. 2. The adjustable ash shovel of claim 1, wherein the blade is substantially flat. 3. A pitch adjustable ash shovel for removing ash debris from an associated ash laden surface, the adjustable ash shovel comprising: a blade comprising a transverse forward edge, the forward edge of the blade comprising a contact surface for slideably engaging the associated ash laden surface;a pivot secured to the blade, the pivot comprising an axis of rotation generally parallel to the forward edge of the blade;a handle including a first end and a second end, the first end being rotatably mounted to the pivot;an adjustable retention assembly secured to one or more of the pivot, the blade, or the handle;wherein the pivot is slideably engaged in a slot in the first end of the handle; and,wherein the pivot and the adjustable retention assembly cooperate to alter the pitch of the blade with respect to the handle. 4. The adjustable ash shovel of claim 3, wherein the handle includes a biasing element operatively disposed between the pivot and the handle. 5. The adjustable ash shovel of claim 4, wherein the adjustable retention assembly includes a notch plate and a notch pin, the notch plate being secured to one of the handle or the blade and the notch pin being secured to the other of the handle or the blade, the notch pin being selectively engageable with one of a plurality of spaced apart notches in the notch plate so as to incrementally adjust a pitch angle of the blade with respect to the handle. 6. The adjustable ash shovel of claim 4, wherein the adjustable retention assembly includes a first rack member and a second rack member, the first rack member being secured to one of the handle or the blade and the second rack member being secured to the other of the handle or the blade, a plurality of teeth of the first rack member being selectively engageable with a plurality of teeth of the second rack member so as to incrementally adjust a pitch angle of the blade with respect to the handle. 7. The adjustable ash shovel of claim 4, wherein the adjustable retention assembly includes a threaded locking assembly, the threaded locking assembly including a first threaded member and second threaded member, the first threaded member being rotatably secured to the handle and the second threaded member being fixed with respect to the handle, such that a rotation of the first threaded member about a longitudinal axis of the handle either tighten or loosens the handle with respect to the blade. 8. A pitch adjustable bi-directional shovel for the removal of debris from an associated debris laden surface, the shovel comprising: a substantially flat blade including a forward edge and a rearward edge, each of the forward edge and the rearward edge of the blade comprising a contact surface for slideably engaging the associated debris laden surface;a pivot secured to the blade;a handle including a first end and a second end, the first end being rotatably mounted to the pivot;an adjustable retention assembly secured to one or more of the pivot, the blade, or the handle, wherein the pivot and the adjustable retention assembly cooperate to alter the pitch of the blade with respect to the handle so as to maintain the blade in general parallel orientation with the associated debris laden surface; andwherein the contact surface of the forward edge slideably engages the associated debris laden surface when urged in the forward direction and the contact surface of the rearward edge slideably engages the associated debris laden surface when urged in the rearward direction, thereby accumulating the associated debris on the blade of the shovel in both of the forward and rearward directions; and,wherein the blade includes a plurality of walls disposed along an upper surface of the blade that define a plurality of debris retention compartments.
