I have a head and a tail, but no body. Do you know what am I?

Question

My head and tail both equal are,
My middle slender as a bee.
Whether I stand on head or heel
Is quite the same to you or me.
But if my head should be cut off,
The matter's true, though passing strange
Directly I to nothing change.
What am I?
