I purchased this hammer at a farm auction about 15 years ago and have yet to find any info about it or what it was used for. The head portion is like that of a lathe hammer but the "hooked blade", which can be struck with another hammer for cutting or splitting, completely baffles me.
The hammer was made by the ... L. A. Sayre & Co., Newark, NJ, and is stamped as said on the side of the blade. Any info or guesses would be appreciated.
