Abstract

The invention relates to an interface between a knife and a knife holder, wherein the knife and the knife holder are designed such that the knife can be mounted on the knife holder in such a way that the knife is initially positioned on the knife holder in the axial direction, and then by rotating either the knife relative to the knife holder and/or the knife holder relative to the knife, the knife is locked on the knife holder with respect to the axial direction, wherein the knife has a single central fastening opening which is delimited by a knife edge region, and the knife holder has a fastening section for the fastening opening of the knife, which is delimited by a holder edge region.
