Description: |
| Described as "a new and useful improvement upon Orval Percival's Patent (of East Haddam, CT) for making gimlets." The referenced patent is Orville Percival's 1835 patent 9,169X. The improvement here 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. |
