3D Model: A Futuristic Thin-bladed Katana With A Fully White, Slightly Glowing Blade, Elegant And Precise Like A Razor. The Blade Is Long And Slender, Maintaining The Traditional Katana Curvature But With A Sleek, Minimalist Edge. Include Subtle Glowing Runes Or Light-etched Circuitry Along The Blade To Give It A High-tech, Cyberpunk Aesthetic. The Grip Is Black, Tightly Wrapped With Textured Leather Or Futuristic Material, With Small Accents In Silver Or Red. The Tsuba (guard) Is Slim And Angular, Possibly Inspired By Abstract Geometry Or Light Patterns. The Overall Design Should Feel Like A Fusion Of Ancient Samurai Craftsmanship And Advanced Sci-fi Technology — Clean, Thin, Stylish, And Deadly. Inspired Loosely By A Glowing Digital Sword But With A Much Slimmer, Refined Silhouette.
