WEIRD HAMMER

[jabberwoki]

Saved this from the scrapper or worse.
Any clues as to it`s intended use?

[skipskip]

not a hammer, its a "struck piece" used by blacksmiths  your apprentice holds it by the handle and you whack it with an actual hammer.

Not sure what this particular one does

Cool!

Hello, jabberwocki and skip . I think that profile  is called  a fuller. And I agree that it is a struck tool!

[moparthug]

Looks like it's been hammered on, could it be a body hammer of some sort? Beat that wrecked '38 Chevy back into submission?

[jabberwoki]

You don`t need a hammer to beat a chebby up just some harsh words will do the trick.

Looks like a hardie hole tool that's been beat on outside of the anvil

Hello, Sudsy. One of the photos shows a broken handle still in the eye!

[Sudsy]

So it does

Now I'm go with an autobody shop hammer

Hello, Sudsy. I'm sticking with what Skip and jabberwoki  said. The tool was held by the handle by one person and placed where needed. Then it was struck by another person , remember this is hot steel being formed. Also , I am pretty sure that the 1-1/2 on the piece shown is either the size of the fuller , or the width of the fuller head. Auto body hammers are not usually marked for size. Figure D-1479 shows a fuller with an eye for a handle, this tool is meant to be struck by another forging hammer. Clicking on the photo will orient it to the correct position.

I jumped to that conclusion too initially until I saw the handle hole !!!!

[jabberwoki]

Ok so vintage?

Absolutely a hammer as evidenced by the hole for the hammer. Note, it is not a round hole either, but the commonly found on hammer heads, elongated.

It is not a hammer.  It is called a struck anvil tool; a top fuller in this case.  You hold it on top of the work, usually with a bottom swage hardie tool under it, and then hit this tool with the hand sledge.  It takes three arms to perform this function.  That is why most blacksmiths had apprentices/helpers and why someone invented a trip hammer.
