Old tools and one whatizzit?

[Sevenhills1952]

Granddad next door was unusual I guess being a machinist, mechanical engineer, MD, D.O., and these are some of his tools.
The one I'm not sure is the first one in my hand, bottle opener looking.
Other are the odd stamps...thunderbird, ********, fluted one with die, etc.
Craftsman 4" wrench.

What you've got there is a Keen Kutter alligator wrench.

Usually used by pipefitters for turning air and water piping on locomotives.

not that 1, that 1 was in the pocket of a tradesman that needed a multitool that size.
