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 include: a) providing a power operated rotary knife including an annular knife blade rotatable about a central axis and defining a central open area; 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 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 moving one of the rotary knife and the chicken paw such that the cutting edge of the blade slices a layer of the metatarsal pad thereby removing at least part of the undesirable portion.
