THE ONE BLADE THAT CAN KILL WOLVERINE WAS FORGED FROM HIS OWN RAGE!

The Featured Fact

Wolverine commissioned the weapon most likely to end him — and supplied the raw material from inside himself. In Wolverine Vol. 3 #40 (2006), by Daniel Way and Javier Saltares, a grieving Logan travels to Japan after the murder of his pregnant wife Itsu and asks the legendary swordsmith Muramasa for a blade unlike any other.

Muramasa agreed, on one condition: the steel needed an edge no ordinary metal could hold. The smith drew the rage out of Logan’s own soul, distilled it, and bonded it to the blade — the forging sequence retold in the gallery page below, where Muramasa extracts that fury and hammers it into the Muramasa Blade.

The result is a katana whose cuts resist healing factors, slowing even Logan’s regeneration to a crawl. He proved the point in Wolverine Vol. 3 #55 (2007), using the blade to finally decapitate Sabretooth — then handed the sword to Cyclops, as insurance in case Wolverine himself ever needed putting down.

Why It's Obscure

Every other weapon bounces off Logan’s healing factor eventually; this one works because, spiritually speaking, it is Logan — the angriest part of him, sharpened.

2006

The commission. Way’s Wolverine #40 sends Logan to Muramasa in the wreckage of his life with Itsu. Most men order a sword; Logan ordered a verdict on himself.

THE FORGING

Soul steel. Muramasa extracted the rage from Logan’s heart, reduced it to a single drop, and bonded it to metal — forged, refined, sharpened. The blade is a blood relative.

2007

The proof. Sabretooth’s head came off in Wolverine #55 and, for once, stayed off — the Muramasa Blade’s wounds heal at a drastically reduced rate. Logan then gave the sword away, to the one man he trusted to use it on him.
