What are these tools used for? The head appears to be copper and there are various sizes.
Those are irons used to heat stuff, e.g. for soldering.
Yes, old fashioned soldering irons. Heat them with a torch, or in the fire, or forge, or whatever, then get to work.
Old soldering irons as others state. Its pretty neat seeing old timers using those on copper gutters.
Soldering irons for sheet metal work.
Wow! Thanks everybody. I guess that’s a blinding flash of the obvious when you think about how they did it before electric soldering irons.
I’ve used something vintage like these ages ago, for soldering organ pipes from pipe organs. Those were not copper. The older pipes were a more brittle zinc and the newer ones from the 1950s were a tin/lead alloy. much easier to work with other than their physical size.
