Because the point of a sharp nail does not encounter as much resistance as a blunt one
So when you go to hammer it in the wood it goes in properly, if it had a blunt end it wouldn't ease in as well. Hope this helps :)
leverage
The momentum and energy is transferred to the nail.
The effort force is where you are holding the hammer to pull the nail.
when you raise the hammer at the top of your upswing the hammer has potential energy when you lower the hammer to hit a nail , the hammer has potential energy.
Pointed nails part the fiber of the timber. But ... this is exactly why you do not want to use sharp nails. The sharp nails push the fibers in the wood grain apart causing the wood to split along the grain. A blunt nail crushes through the fibers leaving the grain intact.

Because they do not have an edge or point that is sharp, they are less accurate and less refined. If you must fix a blunt nail, drill a much smaller hole first
The sharp point tends to work as a wedge and move the fibers off to the side. A blunt nail has to cut the fibers in order to go into the wood. This is because of pressure.
leverage
a blunt knife has larger surface area than a sharp one. Hence force applied will have its effect on larger area causing it difficult to cut vegetables.(its just like : a nail is hammered into the wall from its pointed side....if tried to hammer on the opposite side the result will be nothing.Aki ...
I will strike the nail with the hammer. I strike the nail with the hammer. I struck the nail with the hammer. I have struck the nail with the hammer.
Make The Handle Longer
the long handle provides a greater lever effect
hammer - nail screwdriver - screw
Turn the nail upside down on a hard surface and hit it with your hammer. A dull nail breaks through the wood and a sharp one can split the wood.
