Abstract
An auger is produced from a material such as plastic. The auger includes a shaft with a first pointed end having a thread member thereon. A second end of the auger includes an opening. Handles extend perpendicularly from the shaft and near the opening. The threads are formed in a manner to facilitate removal of the auger from a mold in which the auger may be formed using a plastic-type material. On opposite ends of the shaft, the thickness of the thread is increased to provide a clearance for the thread so that the completed auger may be readily removed from the mold.
