I’ve been using a very personal way of re-using canning lids which is strictly forbidden by their manufacturers. I punch a tiny hole in the lid with a small nail, I let hot water fall on the jar to loosen the lid (dilatation) then I can easily remove it. I will then solder the hole with a drop of tin and re-use the lid (3 or 4 times by now). Of course I don’t advise anybody to do it but if someone has a soldering iron at home and feels adventurous…
