Stomping! Everyone has an experience of getting a wall damaged or a nail bent as we do not drive the correct spot. The head of a nail is small. Putting a sighting plate on this small nail head is an attempt to facilitate people to correctly drive the nail. The sighting plate is always available anytime, anywhere in driving the nail with that attached a hammer.
