In combination, a toroidal rotary knife blade having a sharpened circular lower edge and an upper blade holder engagement section and a blade holder for the toroidal rotary knife blade. The blade holder includes a generally toroidal blade holding ring having an upper gear-engaging section including a plurality of gear teeth formed thereon for intermeshing with a drive gear and a lower blade engagement and retention section adapted to receive and retain the toroidal rotary knife blade therein. The blade holding ring is constructed of material selected from the group consisting of plastic, polyvinyl chloride, polyethylene, polypropylene, polystyrene, vinyl, and polyethylene terephthalate. Finally, the generally toroidal blade holding ring is operative to reduce noise and vibration emitted therefrom during rotation of the generally toroidal blade holding ring by a drive gear due to the use of plastic construction materials.
