Before you pick up a hammer tool and start swinging, you want to make sure you have the right one for the job. And you should never use one with a loose or broken handle, because the head could fly off while you’re using it. You also don’t want to use a hammer with a chipped or cracked head, because you could cause an accident. You want to hold the hammer like you’re shaking hands with someone. And if you need more control (such as when you’re starting a nail), grip the hammer closer to the head. If you need more power, grip it closer to the end of the handle.
