<p>The invention concerns a clamping device for use by individuals when cutting sheet material, such as planks or boards. The device comprises an upper clamping surface (1), a lower clamping surface (2) and a projection (3) extending downwardly from the upper clamping surface (1) into an aperture (4) of the lower clamping surface (2). In use, the clamping device is slipped onto an end face of sheet material after an initial cut has been made. The user can then proceed to extend the saw cut using a hand saw, jigsaw etc., safe in the knowledge that the clamping device will prevent excessive vibration of the cut ends of the material and that the projection (3) will maintain the gap (known as the kerf) between the cut open.</p> |
