Ok hear me out.

I know this sounds like it ought to be illegal. But its a genuine hobby! People got really into this during lockdown (pun intended) and I've been told it's quite cathartic.

It's pretty much a teach-yourself kind of hobby. There are tutorials on youtube & you'll need to buy a set of tools.

If you enjoy puzzles, this could be for you. Plus it may come in handy one day, if you forget your keys or plan to rob a safe.
