A hand-held vibrating nail trimmer which facilitates the management of finger or toe nails. The trimmer contains a small electric motor which vibrates a serrated blade placed on top of the nail. The vibratory action of the blade penetrates the relatively brittle surface of the nail, thereby trimming the nail. Because of the flexible nature of the underlying skin and tissue, it will move in unison with the blade and therefore resist being damaged.
