BONNEY'S PAT. AUG 2. 70 ADJUSTABLE TENON CUTTER

Very early patented tenon cutter or hollow auger in excellent condition. Charles S Bonney of Syracuse, New York was the patentee. Cutter is complete with the original depth stop and is virtually identical to the patent drawings. Used in a brace and likely one of the very first patented adjustable hollow augers.
