I don't know is he really sawing his rackets, but this can help:
He didn't stay in Olympic village - he, and whole Serbian tennis team, have rented houses near Wimbeldon complex.
And I think that every house have some kind of saw in garage or in some tool shed. So possibility to have saw is very huge... but as I said, I don't know is he really doing that.
Hmm, you sure Divac went to the house?
But could be.
why didn't he just use a laserbeam to melt it in two pieces?
Hmm it makes me wonder what kind of saw he used? woodsaw, ironsaw, electricsaw? chainsaw would be brutal!
Novak the chainsaw murderer!
