It says in Trelawney's first prophecy that "One must die at the hand 
of the other."  That is interpreted as Voldemort must kill Harry or 
be killed by Harry.  But, Voldemort has a third hand.  It is the 
silver hand he gave Pettigrew.  Maybe, the prophecy was talking about 
Pettigrew's silver hand that could kill Harry.
