Unusual Keen Kutter hammer, engineer’s pattern head

Description

This hammer bears the Keen Kutter mark used by the E.C. Simmons Hardware Company.  It’s a mass of contradictions.  The head is similar to the engineer’s hammers used in metalworking,  but is small and light enough that it might be a tack hammer.  On the other hand, the shaft is quite thin and the handle fairly small, most resembling certain types of piano-tuner’s tools. There are a few very tiny chips around the edge of the face; otherwise in   I’ve never seen another like it.  It’s intriguing and unusual.
