Abstract: An apparatus and a method for cutting deep-frozen foodstuff, in particular fish, in the form of square plates 4 into a plurality of square rods 15. The apparatus consists of a circular saw which is provided above a closed table top 1, and on the shaft of which are clamped, between spacer disks 6, individual saw blades 5. With respect to the thickness of the plates 4, the circular saw blades 5 have a large diameter.
