Judging by the paraphernalia, this is what happens after a Finnish amateur radio operator retires and suddenly has way too much free time.

There are a few members in my amateur radio club that have a (~200) collection of CW keys. Bugs, paddles, straight keys, etc. Some very obscure ones (only one or two made), some old ones, strange designs, etc. They'll occasionally bring one to a club meeting and pass it around for people to examine and try.
