Yesterday I was in M's shop... "borrowing" ... some tools. (I'll give 'em all back when I'm done - I swear!)
But under a pile of rubbish and behind the work bench, I found some oddities and I don't think even The Internet's Handiest Handyman knows what they are!
You know the rules: no Googling, and no whispering or prompting from the peanut gallery!
No cheating! Good luck!
