Homebrew PCBs

I thought Wikipedia would have the answer, but it does not.

I'm guessing it predates soldering - as we have clothes "irons" (which  
may have actually been iron (wikipedia again deficient)) and the  
phrase "strike while the iron is hot" - which I take to mean a  
branding iron and they usually are iron 'cos that's what guys on farms  
have handy.

Just a generic phrase for hot metal from back when there weren't many  
around?

It's also just occurred to me that you'd want the handle to be iron  
because it doesn't transfer heat well, and it's probably a bit hard to  
fuse iron and copper manually.
