I'll disagree with you on Jason's iconic mask being a notch it two higher.
It is using a mask that nhl teams the goalies and other hockey teams use to use more than 15 years before Jason Voorhees started to use it.
Freddy's glove was something original and creative because that isn't a real world item or thing before the movie was made.
It's astronomical because it 1st appeared in a nightmare on elm street movie used by Freddy Krueger that after showing it to any person no words mostly anyone would recognize or know it's Freddy Krueger's bladed glove.
You could show the old school hockey mask, and unlikely almost anyone would know or recognize it's the Jason Voorhees iconic mask from the Friday the 13th movie series since others might recognize it as a item from Full House, hockey item, etc because it's not a item that 1st appeared in the Friday the 13th movie series.
