Anytime you need a grip on things, you need the Magnetic Finger. The powerful magnet on your fingertip allows you to hold or retrieve any small (or large!! this is an M12x50 bolt) ferrous metal object with precise control. Ideal for use in tight spots and hard to reach places - and when you can't afford to drop it..
