Patent

CA 2704666

The invention is a tool for lifting building materials, such as shingles, while extracting nails that fastened those materials. The slots that grip the nails are a concatenation of overlapping holes, for smooth insertion of the tool past the nails, and the envelope of the tool is a surface of curves for smooth insertion of the tool under the building materials. The bottom surface is a rocker that provides a moving fulcrum for prying out the nail, giving maximum force when the nail is first gripped and smoothly moving to maximum speed of extraction as the fulcrum moves back towards the user.
