<p>A push-pull DIY cutter for sheet material, such as mat and foam board, utilizes a blade-mounting handle that is pivotable from a null position in both of two opposite directions, so as to alternatively bring into operative position a blade element spaced to either side of the null position center line. The cutter is adapted to slide along a clamping bar and to be reversible thereon, for ambidextrous use and maximum-width border cutting, and different forms of blades can be employed interchangeably.</p> |
