Invention Concept This tool resembles a typical "T"-square; however, it has an open channel all along the straight edge. The top edge of the square is designed to be placed over a pre-measured length of aluminum. A typical razor knife can then be inserted into the channel and simply run down the channel, thereby scoring the aluminum coil. The square can then be removed and the aluminum can be bent at the score mark until it separates.
