The Outside Bevel is created by cutting into the fallout surface with the blade angled at 45°/52°, thereby slanting the bevel under the fallout surface. The matboard core is not visible from the front.
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.
