Nice rendering. My guess are a pice of either burned wood or stone with moss on.
I'm sorry, wrong answer :P
It's something very old, not exactly made of stone... and is more or less 1 meter long.
hehe thank you very much for your comment :)
A roman bronze sword?
you were not far from the solution, but it's a viking age sword, Vijay Pinglay guessed right!
tempi di lavoro e di rendering?
scusami non avevo letto la pagina relativa al progetto, è comunque notevole :)
