A nail puller mounted on the side of the head of a hammer. The nail puller may be incorporated into a metal hammer head and consist of a groove mounted substantially in line with the handle of the hammer. The nail puller consists of a V-shaped opening suitable for engaging various sizes of nail heads or shanks. The nail puller is located on the side of the hammer, such that the nail is engaged when the hammer is laid nearly parallel to the work surface. The position of the nail puller gives the user nearly 180 degrees of rotation to remove the nail.
