Abstract:
1. A method for trimming an undesirable portion of a metatarsal pad of a chicken paw using a power operated rotary knife, the steps of the method comprising: a) providing a power operated rotary knife including an annular knife blade rotatable about a central axis and defining a central open area, a blade housing supporting the blade for rotation about the blade central axis, and a handle assembly extending from the blade housing including a drive member engaging and rotating the blade, the blade including an annular body with a blade section at a first axial end of the blade and gear teeth engaged by the blade housing drive member at a second axial end of the blade, the blade section including a lip extending below a lower surface of the blade housing and radially inwardly toward the blade central axis, the lip defining a radially inner surface having cutting edge at a distal end; b) moving one of the rotary knife and the chicken paw with respect to the other to position the rotary knife with respect to a bottom of the chicken paw such that at least a part of the undesirable portion of the metatarsal pad is within the central open area of the blade and the cutting edge of the blade is proximate to a periphery of the undesirable portion; and c) moving one of the rotary knife and the chicken paw with respect to the other such that the cutting edge of the blade slices a layer of the metatarsal pad thereby removing at least part of the undesirable portion.
