I try not to collect modified tools. But sometimes the modification has not taken away the use of the tool, some masterfully done.
First pic. Snap on BH16 bass hammer, someone took a old beat up head and turned it into a useful tool.
Second. A model 598 Blue Point body hammer, one end changed to a dome.
Third. Snap on RS-4 rat. a more useful handle was added.
That RS-4 is a nice mod. I could see where that would be very useful.
Nice score on all of them.
I like the body hammer mod. Made a very nice finishing hammer out of that flat top.
