[Fallout] Why do the domestic Mr. Handy robots come equipped with a flamethrower and buzzsaw?

Surely there's more civilian friendly tools they could be equipped with if they're expected to clean houses and change diapers, right? Maybe, I dunno, two more hands instead?

Remember- the fallout world was on the brink of war long before the nukes started falling.

"Able to defend itself and you in an emergency" would be a perfectly valid selling point for a domestic robot, even if the polite nature of society stopped them saying it outright.
