In the small town where my mother lives, people do exactly that.
But if you lock your door and fasten your seatbelt, why is it then laziness to use a tsuba? I trust my partner's control, but I don't *depend* on it to protect my hands.
In my example the tsuba represented the safe town so those people are not relying on the tsuba.
Who said anything about trusting your partner to protect your own hands?
