ABSTRACT:
The pry tool of the present invention is utilized for dislodging concrete forms from set concrete. It includes a fulcrum assembly and pivoting leveraging member in operative juxtaposition to the fulcrum assembly. One end of the fulcrum assembly engages a first single concrete form member connecting slot and the opposite end of the fulcrum assembly connects to a pivoting leveraging member. The leveraging member is parallel and set off from the fulcrum assembly in direct alignment with a second adjacent concrete form. The leveraging member is hand manipulated to exert force against the second adjacent concrete form forcing the form inward into the concrete wall. This causes a leveraging action with the engaged end of the fulcrum assembly forcing the first concrete form outward away from the concrete wall and thereby separating the form from the wall.
