ABSTRACT:
A nail driver comprising a generally T-shaped body having a barrel, a hollow plunger slidably reciprocable in the barrel, a rigid stem on the body extending centrally along the inside of the barrel into the hollow plunger, a spring biasing the plunger to an extended position forward past the front end of the barrel, a magnet tip loosely coupled pivotally to the stem at its front end and having saw teeth on the bottom, and an insert carried by the plunger and having saw teeth on the top. With the magnet tip holding a nail extending lengthwise inside the barrel and the front end of the plunger held against the object into which a nail is to be driven, when the body is pushed forward along the plunger toward that object, the saw teeth on the magnet tip ride bumpily across the saw teeth on the insert, causing the magnet tip and the nail it holds to vibrate up and down as it is driven into the object.
