...when the metal, unprotected bit of a Cropadile hits you full whack in the head after falling from a great height... it flipping well hurts! And it leaves a golf ball sized lump along with a lingering feeling of tenderness and nausea. I don't recommend it.Good news is though - when it bounces off your skull and smashes into your glass topped desk... it wont smash the glass. Oh no - you can rest assured that wont even chip! So - yeah, win on that count!
