Answer:
Often held but never touched. Always wet but never rusts. Often bits but seldom bit. To use it well you must have wit.
I scribble forms of the finest letter, And repel elements of the harshest weather. I am an arrow-aimer and a dust-breaker.
They made me a mouth, but didn't give me breath. Water gives me life, but the sun brings me death.
I'm light as a feather, yet the strongest man can't hold me for more than 5 minutes.
A kind of weather that comes your way, but add a "D" and it will run away
What never gets any wetter no matter how hard it rains?
