Abstract
The masonry cutting device generally includes a portable, lightweight frame having an integral upper cutting edge and a center space, a lifting device supported by the frame within the center space and below the upper cutting edge, wherein the lifting device moves a lower cutting edge towards the upper cutting edge for cutting a masonry item between thereof. The lower cutting edge is attached to a guide member which includes slotted ends for travelling along the frame to keep the lower cutting edge in alignment with the upper cutting edge. The lifting device is generally comprised of a shortened, hydraulic jack having a release member, manually-operable handle, and optional spacer. Also included are bias members for exerting a downward force upon the guide member and a catch tray generally comprised of a wired grid that is removable upon the frame and used to catch the cut masonry items.
