Soldering irons can be used to repair/reinforce themselves

SDL 0.A Experimental, 9853c2b (build 2359), Windows 8.1

I only have one charged soldering iron, and it is bound to p.
[ i ]nventory -> [ p ] (s. iron) -> [ a ]ctivate -> [ p ] (s. iron)

“You practice your soldering.”
“You damage your soldering iron!”
“You repair your marked soldering iron!”
“You make your soldering iron extra sturdy.”

…So do all soldering irons secretly have non-euclidean geometry or is it just this one?

That’s a bug. Thanks for reporting.

I have already reported this one. It’s working with all such tools.
