I got this hammer,,

[john k]

Found this at a junk shop, the only stamping is what looks like 1 lb.  but hammer is closer to 2.0 or 2.5 lbs.   Almost looks like a 3.5 lb. ball peen that's been turned down on a lathe.  Any idea of type name, or usage?

Is it steel?  Does a magnet stick to it?  It has the appearance of lead.

We call that an engineer's hammer around here.
Used like any peen, except there isn't a peen side, just 2 flst faces.
