No joke: My dog's name was "Guess". His sister's name was "Who". At the same time, we had a cat named "What do you think?"
Newcomer: What's your dog's name?
Newcomer: I've no idea.... Captain?
Me: No, Guess!
Newcomer: Heck I don't know... what's the other one's name?
Newcomer: *sighs* What's the cat's name?
Me: (well, you get the idea)
....aaaand so on. It was fun stuff!
Meanwhile, different type of tool, but what if you called him Jack - short for Jackhammer?
Swamper? (my cow's name)
Bogger? (other cow's name)
Okay, so those aren't tools specifically, but they're cool
Pickle.... that'll have anyone wondering how he's named after a tool
