Tomioka Yoshiyuki Demon Slayer Nichirin Sword – Handmade T10 Steel Cosplay Katana

Tomioka Giyu Inspired Katana

Demon Slayer Replica Sword – Real Handmade T10 Steel Blade

Inspired by Tomioka Giyu (富冈义勇), the Water Hashira from Demon Slayer: Kimetsu no Yaiba, this sword faithfully recreates the clean and restrained aesthetic of his Nichirin Blade while being constructed as a real, functional katana.

Tomioka Giyu is known for his calm demeanor, discipline, and mastery of Water Breathing techniques. His sword reflects this personality—simple, balanced, and practical rather than flashy. This replica captures that spirit while maintaining authentic katana structure, making it suitable for collection, display, cosplay, and light cutting when sharpened.

Character & Weapon Design

In the anime, Tomioka Giyu’s Nichirin Blade emphasizes functionality and restraint, matching his serious and quiet nature. The sword’s minimalist design, white handle wrapping, and contrasting red sageo are instantly recognizable to fans.

Unlike decorative wall-hanger replicas, this sword is built with full-tang construction and traditional proportions, bridging the gap between anime accuracy and real sword craftsmanship.

Blade & Steel

The blade is hand forged from T10 high carbon steel, offering excellent hardness, edge retention, and durability. After oil quenching and tempering, the blade is finished with a mirror polish, giving it a clean, refined appearance consistent with the anime design.
