Salazar's dagger?

We are already well acquainted with Godric'¨s silver sword set with 
egg-sized rubies in the handle; the Gryffindor weapon. I wonder 
whether we've already met Salazar's weapon? Anyone else noticed the 
silver dagger at the end of GoF?

Quote: "He [Wormtail] pulled a long, thin, shining silver dagger from 
inside his robes... 'Flesh - of the servant - w-willingly given - you 
will - revive - your master.'" (GoF p. 556 UK Ed). Wormtail then 
proceeds to cut off his own hand.

No mention of any precious stones or the like on the handle of the  
dagger, but apart from that I find it interesting that it is made of 
silver; not just steel, signifying it is expensively wrought... Any 
thoughts as to whether this could be our first glimpse of the 
Slytherin weapon?
