The concept of using a heavy object to hit another object predates written history. What started as rocks tied to the end of a stick has evolved into a wonderful duo, the hammer and the nail. But it seems the hammer was always plagued with hitting something it was not supposed to hit.
Today everything seems to work great until you try to swing and either miss or hit something else damaging the nail, the object being nailed, or even your thumb. OUCH!
The nailed It Tool makes it easier to hit the nail and direct it into hard to reach placed with less chance of bending the nail, damaging the wall, or the object being secured. With a larger strike surface and by moving your hand away from the surface it also reduces chances of your hand being struck between a "rock and a hard place"
