A knife shaft assembly is disclosed for use in a rotary die cutter. The knife shaft assembly includes a rotatable die shaft having an outer circumference and having a defined width. At least two die cutting inserts are mounted on the outer circumference of the die shaft. Each of the inserts has a first surface and a knife formed about the periphery of the first surface. The knife shaft assembly also includes a compressible material positioned between the die cutting inserts which prevent the buildup of material waste there between.
