Sekiro’s Mortal Blade (Fudo / Undead Severance Katana) – 1:1 Game-Accurate Hand-Forged T10 Crimson Steel Replica

Unsheathe the Crimson Blade. Sever the Chains of Immortality.

Forged for shinobi who have walked the perilous paths of Ashina, this 1:1 scale replica of Sekiro’s Mortal Blade (Fudo) transforms the legendary god-slaying weapon from Sekiro: Shadows Die Twice into a tangible, hand-forged masterpiece. Whether displayed on your wall or held in hand, every detail reflects the dark, lethal beauty of the sacred weapon meant to strike down the immortal.

Why Sekiro Fans & Collectors Choice This Blade

  • 1:1 Game-Accurate Crimson Aesthetics: Crafted to mirror the blade drawn from the Senpou Temple inner sanctum. Features a custom red-heat-treated carbon steel finish that radiates the lethal aura of the Undead Cut without compromising structural integrity.

  • True Hand-Forged T10 Carbon Steel (58 HRC): Built using high-grade T10 tool steel, oil-quenched and tempered to achieve an optimal balance of hardness (58 HRC) and flexibility for functional collectors.

  • Authentic Shinobi Tsuka & Guard: Wrapped in crimson ray-skin beneath black leather tsukamaki for an authentic tactile feel. Features the iconic antique-silver and black flower-petal tsuba (guard) and the functional ring pommel unique to Sekiro's sidearm.

  • Full-Tang Construction: Formed from a continuous piece of steel extending through the entire hilt, secured with double mekugi (bamboo pegs) for battle-ready stability and realistic weight distribution.

  • 8-Stage Hand Polished & Geometric Kissaki: Ground by skilled artisans through eight polishing stages to reveal sharp lines, crisp edges, and a clean, defined blade tip.
