Answer:
I am shared by goats devils and unicorns.
I am a daily ritual involving using a metal tool on the body
My voice is tender my waist is slender and I'm often invited to play. Yet wherever I go I must take my bow or else I have nothing to say.
I am two-faced but bear only one. I have no legs but travel widely. Men spill much blood over me. Kings leave their imprint on me. I have greatest power when given away yet lust for me keeps me locked away.
I cannot be other than what I am, until the man who made me dies. Power and glory will fall to me, only when he last closes his eyes.
I flow from the Homerβs mouth when he sees doughnuts.
