What this video covers

SKS Props walks through a full foam fabrication build of Pyramid Head's iconic Great Knife from Silent Hill 2, referencing imagery from the remake for game-accurate proportions. The finished prop is constructed from HD-Foam, keeping the oversized blade surprisingly lightweight despite its dramatic scale. Surface texture is achieved using Flex Seal as a base coat, followed by layered acrylic paints and specialty mediums for a battle-worn, rusted metal appearance. Free downloadable PDF templates are provided to help builders of any level get started.

Key takeaways

  • Free PDF templates are available on the creator's website for accurate scaling
  • HD-Foam keeps the large prop lightweight — finished piece is approximately 1.5 lbs
  • Flex Seal applied over foam creates a convincing rough metal texture base
  • Layered acrylic painting with pumice and ceramic stucco mediums adds realistic wear and grit
  • Silent Hill 2 remake reference images were used to ensure game-accurate details
