Abstract
Abstract A tool adapted for use in the dental art for denture prosthetics and distinctively to perform relatively faster heat softening of the gum-shape piece of wax currently used to take an imprint of one's mouth. This tool includes an elongated handle, a service blade and a multi-bladed spatula with the service blade either parallel to the blades of the spatula at one end of the handle or at the opposite end of the latter relative to the spatula. The blades of the spatula merge into a common shank engaged into a common aperture in one end of the handle and are preferably rigidly interconnected intermediate their ends.
