Just been doing a little searching of our favorite slashers butcher knife and managed to find pictures of only three different ones online all listed as Case & Sons 102-12”. The reason I am making this post is to point out that all three share differences in handles and some even very slightly in blade shape. This obviously isn’t something uncommon for manufacturers back in the day of an item of the same make/model and just brings me to question what exact look was the knife used in H1.
Just going off of these photos of the three different ones I think #3 matches the most to the movie knife handle wise and blade shape wise. The blade has a really symmetrical shape all the way down almost to the point and the handle has that rounded look with the dark cherry finish. This particular knife is also owned by a member here in the forum.
