A ring blade ( 18 ) for use with a rotary knife ( 10 ) includes a first member that forms an annular blade member ( 90 ) having an annular cutting edge ( 96 ) for cutting into material with which it is brought into contact. A second member ( 92 ) is fixed to the annular blade member to provide a drive surface by which the ring blade is rotated. In one embodiment the blade member is machined. In another embodiment the blade member is cold formed from a thin sheet of hardenable steel.
