Abstract
A rotary cutter knife in which a body is provided which is made up of coaxial discs in adjacent relation. Each disc has cutting edge portions distributed about the periphery thereof and in one relatively rotated position of the discs the cutting edge portions align in the axial direction thereby positioning the cutting edge portions for easy sharpening. In another rotated position of the discs, the cutting edge portions are staggered and the cutting load on the cutter knife is thereby distributed circumferentially during working operations of the cutter knife. Cooperating elements of keying means are provided for keying the discs in the two relatively rotated positions thereof.
