It could be coincidence, but there’s an antiquated term for a mace or morningstar, bommyknocker. People on the web seem to attribute it to a children’s book from the 90s, but I’ve found much older uses in the past, both in the UK and in Oceania. Similar to your name and not a very dissimilar tool.
Edit: I guess it’s obvious I skimmed your answer! You’ve already made the connection.
