Answer:
My teeth are sharp, my back is straight, to cut things up it is my fate.
I can sizzle like bacon, I am made with an egg. I have plenty of backbone, but lack a good leg. I peel layers like onions, but still remain whole. I can be long, like a flagpole, yet fit in a hole.
I am round as a bowl, deep as a tub, but all the world's water couldn't fill me up.
Who works when he plays and plays when he works?
What is the thing which, once poured out, cannot be gathered again?
Iām grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
