Description:
Described as "a new and useful improvement upon Orval Percival's Patent (of East Haddam, CT) for making gimlets." The improvement is to make a normal gimlet, and then remove a semi-circular section of the threaded portion so as to create a sharp cutting edge and provide clearance for waste.
