The what???

In the palm of my hand, I hold a fastener divine,

With a pointed tip, secures the parts that align.

A wonder of engineering, this simple device,

With a cross-shaped head that's both clever and nice.

It grips the driver with an iron hold,

And never slips or wobbles, nor does fold.

Simple symmetrical shape, a thing of beauty,

And in the fingers of a pro, it's a worker's duty.

To fasten, to tighten, to hold things together,

In this world of machines, it's a godsend, forever.
