Was filmed using a real Buck Knife 119. Since this film though, the Stab fan-film creators decided to stop using real knives, and do not recommend other filmmakers ever try it.
When the filmmakers decided to start making the Stab movies, Scream 4 had not yet been released. It wasn't revealed until Scream 4 that Stab 5 contained time travel. In light of this, the creators of the Stab Fan films like to think they created their own Stab Universe, instead of directly remaking the Stab films portrayed in the Scream Franchise.
Based off the Scream franchises.
