Answer:
You can catch me but cannot throw me.
A dragon's tooth in a mortal's hand, I kill, I maim, I divide the land.
I can be sweet or sour. I do not rhyme with any other word
If you have me you want to share me. Once you share me you wonβt have me.
I have a head and a tail but no body. What am I?
No matter how little or how much you use me, you change me every month.
