Nail Sword

Item from Chainsaw Man by Tatsuki Fujimoto

The Curse Devil's weapon — a short blade resembling a massive nail that Aki stabs into targets. After enough stabs, the Curse Devil manifests to kill. Each use costs the wielder years of remaining life.

The nail sword is the physical component of the Curse Devil's contract. Stab a target enough times, and the Curse Devil materializes to execute them. The weapon itself is unremarkable — the horror is in what it costs. Every use drains years from the wielder's lifespan. Aki carried it knowing he was trading his future for each kill, which is the most Aki thing imaginable.

Appearance

A short, thick blade shaped like an oversized nail or spike, dark metal with no ornamentation. Functional and brutal — looks more like a tool of execution than a proper sword. Fits in one hand.

Also known as: Nail Sword, Curse Devil's Nail, The Nail
