Kamutoke Replica – 16cm Die-Cast Metal Dagger | Deceptively Heavy

From BlacksmithSONG: the Kamutoke replica in solid die-cast zinc alloy — 16cm (6.3"), 103g (3.6 oz), shipped free worldwide with tracking. It's Sukuna's lightning-calling cursed tool, shrunk down and clipped onto a keyring instead of channeling storms. Don't let the size fool you — this one has actual heft.

What Is the Kamutoke?

The Kamutoke is a cursed tool Sukuna used to call down lightning strikes, described in the story as a tokkosho — a single-bladed vajra. He wielded it in the Heian era and again in the present day, until it was seized and never returned. Ours is a fan-art take on that lightning tool, cast here as a compact blade instead of a classic double-pronged vajra.

Shot by Us

Every photo on this page is ours — shot in our own studio, of the exact piece we ship, keyring included. No CGI, no renders, no supplier images. We shot it close so the cross inlay on the guard and pommel reads clearly, with the books behind it there purely for scale, not staging.

What You're Holding

How Big Is 16cm, Really?

At 16cm (6.3"), the Kamutoke clips onto a keyring without dragging your bag down, or stands upright taking up barely any shelf space if you'd rather display it than carry it. What throws people off is the 103g (3.6 oz) — about three keys' worth of weight packed into something barely bigger than your palm, so it works as a desk paperweight just as easily as a keychain. Check the photo above before deciding which job it gets.

Straight from the Mold

The whole piece is die-cast in zinc alloy as one body — the blade, the cross-inlaid guard, and the wrapped grip texture are all shaped in the same mold, with the keyring loop cast right into the pommel end. The gunmetal-grey finish carries a gold-toned cross motif at the guard and pommel, so the two tones read differently depending on the light. Edges stay blunt straight from the casting — this one's built for a pocket, not a sheath. Curious about the tool it's based on? Read the full rundown on Sukuna's two cursed tools.

It's a fan-made tribute to a Jujutsu Kaisen cursed tool, unofficial and unaffiliated, and it pairs naturally with the Inverted Spear of Heaven, the other special-grade tool from Sukuna's era.

Sukuna carried two cursed tools through the Heian era, and this is only one of them. Hiten was the other — a trident nobody living has ever actually seen him use.
