It looks like a UBE or a Movie Model! Am I correct?
It looks like one of the standard chrome plated tourist models. The one positive is that he knife is shown in 4 or five scenes, and it is portrayed as a tool first and a weapon as a last resort.
i really enjoy a bad sci fi/horror movie
Me too; low budget films have often broken new ground and they can sometimes be very rewarding. Whether it is the annoying but genuinely scary Blair Witch Project, or the shocking gore of Night of the Living Dead, and Texas Chinsaw Massacre, or, It! The Terror from Beyond Space (1958) - more recognizable to us today as the original, if campy, template for Alien(1979).
My favorite one to date is the original version of The Thing From Another World (Hawks 1951). It has a well written script and a rare ensemble cast, that while weak on a whole, comes across as well balanced and pursuasive. The story of people being chased around by a monster is an old one, and this film could have easily turned into another version of Friday the 13. But, instead it introduces you to a large cast of likable characters; there is no need to think "don't open that door", these characters have a healthy degree common sense, and that is what makes the movie scary. The special effects are primitive, but they work, and the fire scene has to be one of the most dramatic squences ever captured on B&W film.
John Carpenter remade the film in 1982 with better special effects and more gore, which was truer to the original short story, but also lacked the characterizations of the earlier version. From the get go you know that most of the cast in Carpenter's film is there merely as monster feed.
