A portable, non-power operated cutting tool for cutting sheets of building materials in a straight fashion without splintering or cracking. The cutting tool includes a base, a blade holder with a blade, a handle with an eccentric cam rotatably connected to the base, and a support arm to hold the building material against the base, where the blade holder moves between an open position and a closed position by rotating the eccentric cam. |
