Answer:
What is full of holes but still holds water
With sharp edged wit and pointed poise. It can settle disputes without making a noise.
I cost no money to use, or conscious effort to take part of. And as far as you can see, there is nothing to me. But without me, you are dead.

White bird, featherless, flying out of paradise. Flying over sea and land. Dying in my hand.
I can only be played on a windy day
