Off-topic, but modern consumer electronics (particularly the cheap 'own
brands' tends to be assembled in thin sheet-metal cases with edges that
will give you a nasty-ish cut if you catch them.

Modern components shouldn't get hot enough to burn you :-). Glassfets are
another matter. And an IC that has developped internal shorts can get hot
enough to burn you, some DRAMs were prone to this.

Yes, I was thinking of bruns from the soldering iron, or something heated
by it Most of the time it's when I am soldering a piece of wire to a
large-ish metal object (pin of a 4mm plug) and I don't let it cool for
long enough before taking it out of the vice. Two nasty burns I;ce had
from such causes were the time somebody tripped over the mains lead of my
soldering iron, pulling the latter back through my hand so I ended up
holding it by the metal shaft (and it was a few seconds before I realised
it), and the tiome I dropped a blob of molten solder on my skin.
