Demon-Killing Knife — Inspired by Supernatural

A fan-made 3D model inspired by the demon-killing knife in Supernatural.

What inspired it

• Series: Supernatural (2005-2020), the Winchester brothers' fight against demons, monsters and worse.
• In the show, the knife first appears with the demon Ruby in season 3 and ends up in the hands of Sam and Dean Winchester, becoming one of their main weapons against demons.
• In the show it is an ancient knife made by the Kurds, one of the few blades that can kill a demon outright. Its blade carries an inscription in an old script.

This model

• 309.3 mm long with a 190.3 mm Bowie-style blade, measured from reference photos and built in real-world scale.
• Five sawtooth scallops on the spine, an edge bevel with a crisp shoulder and an edge that sweeps up in a curve to the point.
• The engraved panel and its inscription are cut into the blade geometry itself (0.13 mm deep), with darker oxide left in the cuts.
• Thin plate guard and a stag antler handle with furrows, pearling, a sanded ring at the guard and a worn crown.
• 1,349,138 triangles in the high-poly version (Blade, Guard and Handle as separate objects), 4K baked PBR textures.
