CHAMPION DeARMENT hammer?

[Twilight Fenrir]

I picked up this (relatively) small hammer at a yard sale today... It seems very well made, and is stamped "CHAMPION   DeARMENT" (no, I didn't miss a "P" and the "E" is capital, but smaller than the others, like DeWalt)  but I'm unfamiliar with the purpose of the pein on this one... It looks as if someone took a normal cross pein, and ground out a semi-circle leaving a fairly sharp edge. But it was definitely manufactured this way...

Does anyone know what I have here?
Thanks

Huh.  It looks like a standard tinner's hammer - are you sure the grind on the cross pein is factory?

Pretty sure... I'm having trouble with my phone uploading the other two pictures I have, one of which shows the pein more clearly, I'll fiddle with it some more when I get a chance this evening.

If it's not factory, it was done by a skilled machinist.

Would later be known as the Channellock Company.  From the picture I see it looks like a tinners hammer that was chipped and ground.

Okay, here's a shot of the pein...

What I would expect to be a positive curved surface is concave instead...

Well, that is a puzzle.  Getting comfy on the easy chair to watch the discussion here - no idea what that shape would be optimal for.

Rolled? Hemmed? Edge on sheet metal????

To finish or close a wire edge.
Seems to me I just had a pliers or tongs marked the same? in the fall of last year?

According to the EAIA Toolmaker's Directory, made between 1927 and 1960.

Is that a guess, or a definitive answer? Certainly sounds plausible. Though I wonder how useful it would be on curved surfaces...

Yeah, I did a little research on that end... Champion DeArment was previously a small smithy that grew to become the Champion Bolt and Clipper Company. In 1923 the company moved to a larger facility, and changed their name to Champion DeArment Tool Company. Then, in 1963 they changed their name again to Channellock, capitalizing on the ubiquity of their patented grove-joint pliers.

Educated guess, haven't seen one like that, but have done lots of wired edges. You are taught to use the chisel end, so did it work? probably wasn't a big seller. Some people modify a linesman's pliers to finish the wired edge, there is a hand cranked set of dies for the easy edgers / jenny's. Probably the closest thing I have seen to the end is the a set of pullmax dies I made to finish the wired edge on a late 20's Chrysler fenders.  I've got ??? about 5 or 6 tinner's hammers none with a concave edge.

Very interesting, thanks!
