Rather than purchase claws from an existing fursuit component supplier, I sculpted my own, then made molds and poured a set in resin for the hands of my suit. I tried to give a good blend of realistic and anthro by giving them decent size and curvature but having their base emerge from the where human fingernails would go. I also sculpted with rings at the base so that they're braced to the fingertip for more realistic motion of the hand.
