I have one, you have one.
If you remove the first letter, a bit remains.
If you remove the second, bit still remains.
After much trying, you might be able to remove the third one also, but it remains.
It dies hard!
I am found in great fields.
With my kin, provide great yields.
Decapitate me with no regret.
What makes me bread is what you’ll get.
Cut once again, again I implore
And you will do this thing evermore.
What have you found from me?
Give me the words above, all three.
