Abstract
A cutting implement employing a pair of rollers placed vertically one above the other, the rollers having sharpened edges that slightly overlap and touch each other at a selected position, forming a cutting point where they touch. When the rollers are rotated, the sharpened edges form a continuous cutting edge for cutting material such as most paper and plastics. The rollers are provided with a degree of toe-in in the direction of rotation to insure that they remain in contact with each other during the cutting process. The rollers are rotatably mounted to a stiff carrier to provide dimensionally predictable location of the rollers with respect to each other, and to insure the smooth flow of material through the rollers as the material is being cut.
