A lot of people ignorantly say that it was a carbon fiber handle Harpy which Dr. Lectern used , but they all seem to forget that CF Harpies were only made in 2005 , FOUR years after this movie was released. It couldn't have been a VG-10 knife since VG-10 was first used on the Harpy in 2002 , a FULL YEAR after Hannibal was released and two years before it was shot in 2000. Thus the knife had to be either ATS-55 or Gin1. The knife in Hannibal props museum Clearly shows a black non - metal handle , which could only be G-10 , because it was the only non metallic handle material used on the Harpy prior to 2001. G-10 Harpies are only serrated edge , so l added two plus two and realized that it was a serrated G-10 harpy. It's more accurate to the books too , where ALL of Dr. Lecter's spyderco knives ( Harpy , civilian and military ) are specifically stated to be serrated. I see no reason for the film crew to deviate from the Book Lecter's preference for serrated blades.
