I'm going to go out on a limb here and suggest that a good proportion of women don't have the kind of upper body strength to take on some of the more labour intensive types of manual work. And that is why tools like Black & Deckers battery-operated auto wrench are useful. Two AAA batteries assist in automatically changing the width which is good for fiddly spaces, it (you) can apply up to 190lbs of torque (the force which tends to cause rotation) and can be used with nuts and bolts up to 1 1/4 inches wide. Can be used without the batteries if required - around $30
