I just realised I still have a little metal scoop I made at school. It was made from what I think is tin plated sheet steel bent in a box bender with tabs that had to be soldered. Getting those tabs properly aligned and soldered was a challenge and there are some *wide* gaps where the solder just didn't bridge them.

It wasn't a show-stopper, because I remember learning to braze some tools for the fireplace later and making tyre levers at the forge. Fun times :-)
