It's because if some Karen sees your kid with a real looking hammer anywhere near actual work, (s)he's gonna rat your ass out to CPS faster than you can snap your fingers.
Similarly for toy guns. The weird look ain't for the kids, it's so some passerby doesn't see the "gun" and call the cops (no matter there is no regulation in most states from making a real gun to look like a toy gun so it's a totally bogus presumption).
