Keencut Simplex THE SIMPLEX IS MORE THAN A STRAIGHT EDGE. It's a lightweight, portable straight edge mounted with a quality cutting head that features utility knife blades. The cutting head permits blade depth adjustment and accepts utility blades that cut to a depth of 3⁄8". Use on a floor or a bench; the Simplex is accurate to within 0.03" over the full length of the cut and is an economical alternative to the Javelin Series 2 or Sabre Series 2. Full-length silicone rubber grip strips protect material and ensure that it is held securely.
