The 45° Front Reverse Bevel Opening is created by cutting into the front of the matboard surface with the blade angled at 45°, thereby slanting the bevel under the matboard surface. The matboard core is not visible from the front. The initial plunge position is determined by the bevel type. The Bevel Type refers to the angle at which the blade cuts the surface of the matboard when it deviates from the 90° right angle cut. The Bevel Type determines the initial blade plunge position. Select Reverse Bevel or Reverse Bevel-Front of Mat from the Current Bevel Type dropdown control to edit this configuration.  See: 45 Degree Front Reverse Bevel Opening Configurations |
