It’s not what you need during your normal day that counts as much as what you might need during a bad day.
My wife’s bag could easily be one of those in that link except hers has a small Princeton Tec LED light attached to the handle of her bag and a SAK and mini LED key chain light clipped to the key leash inside the pocket next to the pepper spray.
She doesn’t use any of it very often but it’s always there when needed.
