I'm just getting into blacksmithing. I found this in the basement of the old house I bought. Can anybody tell me what it is? I'm guess a cold or hot chisel? I don't want to misuse it. It's labeled Warwood 1492 and 3 pounds I believe. I can't find any reference to it on the internet. I looked through a modern Warwood catalog and the number is not used.

Thanks in advance!

Looks like a stone mason hammer. I would search that. 

Looks in good condition and may be worth something to those that do that work or collect the tools. 

It could be a mill stone dressing hammer. If it were tapered at both ends it could be a "mill bill".

Such tools are included in some of Mr. Eric Sloan's books.

The stone masons hammers for rough work would be Bouchard hammers. Such a hammer has one end with raised teeth. It resembles a meat tenderizer.

A sketch of a tool seller's catalogue should display many of tools. (try Considene corp.,  (I hope I have the correct spelling) ).

SLAG.

It's a 3 pound masons straight pein, like Daus said.

Stone masons also used a straight peen sledge with a sharp peen for splitting layered rock.  I have owned several. They differ from other sledges by their narrowness in the body. (The other end has a rectangular face.)

I also have several bush hammers designed for working the surface of hard stones---they look like meat tenderizers.  I have been trying to get  matched set to use for patterning with my screw press.

There is also the stone masons trimming axe that consists of a number of individual pointed pieces held tightly in a metal handle, (an example can be seen on page 52 of Antique Tools our American Heritage, Katheryn McNerney, 1979)

Thanks for all the replys and information!

It looks kind of like what I posted last night trying to find out what it is.
