Answer:
I am a seed with three letters in my name. Take away the last two and I still sound the same.
I can sizzle like bacon. I am made from 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.
Can not be bought, Can not be sold, Even if it's made of gold. What is it?
Men seize me from my home tear apart my flesh drink the sweet blood then cast my skin aside.
Ripped from my ancestors home beaten and burned I become a bloodthirsty killer.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
