A re-centering and holding tool for leather-hard or bisque ware. Designed specifically for trimming, it works equally well with waxing the foot or banding with underglazes or engobes. Three arms position your pot into the center. After an initial one-time adjustment, the Giffin Grip simply snaps on and off your wheel. Includes Giffin Grip, basic and wide slider sets, 2", 4" and 6" arms.
