I picked up an obviously old all-steel corner chisel this weekend.
Thirteen inches long.  Seven-eights diameter shaft. Inch and a half striking surface.  The blades are 3/4".  It is all in one piece.
Was this tool made for timber frame work--barn building, and such?
Haven't seen one on the Interweb.

You are correct in what they are used for.  What is unusual is that it is all metal.  Most have a wooden handle. Maybe it was blacksmith made, he wouldn't have had to make the handle socket this way.

I also have a blacksmith made chisel, although it is not as long. I will try and get a picture up in the days to come...
