Kohaku Extended Kusarigama Kama — 17" Anime Polearm Sickle

This is the Kohaku Extended Kusarigama Kama — a hand-forged 8-inch curved blade on a 17-inch full-tang rosewood handle, finished in 5160 high-carbon spring steel. The longest weapon in our anime kama range, built for the polearm-style fighters: Kohaku (Inuyasha & Yashahime), Madara Uchiha (Naruto), Black Star's chained kama configurations (Soul Eater), and traditional Japanese kusarigama practitioners. With a weighted chain added via our Custom Spec Forge option, this kama becomes a full functioning kusarigama — the chain-and-sickle weapon of the shinobi tradition.

Most kusarigama replicas on the market are wood, foam, or aluminum training pieces. There is almost no hand-forged steel competition in this niche — if you want a real, working kusarigama with full-tang construction and a working blade, this is the page. Order as a single kama, a matched pair via the customisation dropdown, or contact us for the full chain-configured kusarigama build.

Why a 17-Inch Handle Changes Everything

The 17-inch handle is not just longer — it changes what the weapon can actually do. Standard kama (8 to 12-inch handles) are built for fast dual-wield striking. The 17-inch handle on this kama puts it into polearm territory — extended reach, two-handed grip options, sweeping arc strikes, and the leverage required for traditional kusarigama spinning techniques. This is the silhouette you see on Kohaku in Inuyasha when he engages from outside an opponent's reach, and the same proportions used in Edo-period kusarigama training schools.

For shorter kama configurations (Akali dual-wield, Sasori compact, Black Star tactical), see the full anime kama collection. This product is specifically the polearm-extended-reach option.

Specifications

All dimensions and weights are approximate due to the handmade nature of the product. Each kama is individually forged, so small variations in finish, weight, and grain are part of the craft.

Customisation Options

Every kama can be customised before forging. Select your standard options from the dropdown above the Add to Cart button — listed price updates as you adjust your configuration. For chain-configured kusarigama, contact us before ordering for a custom forge quote:

How We Forge This Kama — Step by Step

What Is a Kusarigama? — And How This Kama Becomes One

A kusarigama is a kama with a weighted chain attached to the handle. The chain is used to entangle an opponent's weapon, limbs, or stance before the kama blade strikes. It's one of the signature weapons of the Japanese shinobi (ninja) tradition, and appears across mainland Japanese kobudō schools dating back to the Edo period. In modern pop culture, the kusarigama is most famously wielded by Kohaku in Inuyasha and Yashahime, where it serves as his signature demon-slayer weapon throughout both anime series.

The Kohaku Extended Kusarigama Kama on this page is the kama component of that weapon — the curved 8-inch blade on a 17-inch handle. To turn it into a full kusarigama, the handle is configured with a chain attachment point during forging. Because chain configuration is custom work (chain length, weight, and attachment vary by build), this is offered as a Custom Spec Forge option rather than a standard customisation. Contact us before ordering and we'll quote a kusarigama build to your specification — typical timeline is 2 to 6 weeks depending on chain complexity.

Anime & Cosplay Reference

The 17-inch handle profile of this kama maps to the polearm-archetype anime characters:

• Kohaku (Inuyasha & Yashahime) — direct match. The young demon slayer carries a chain-kama (kusarigama) throughout both series. Order with chain configuration via Custom Spec Forge for the authentic Kohaku weapon build.
• Madara Uchiha (Naruto) — the Ghost of the Uchiha carries a long-handled scythe-kama through his iconic Shippuden battles. For the slightly shorter Madara silhouette see the Madara Reaper Kama with a 14-inch handle.
• Black Star (Soul Eater) — Black Star's chained kama partnership with Tsubaki includes longer-handle configurations. For the leather-wrapped tactical version see the Black Star Tactical Kama with a 15-inch leather-wrapped handle.
• Traditional kobudō & ninjutsu practitioners — for kusarigama training and demonstration use, this kama with chain configuration matches Edo-period mainland Japanese kobudō proportions.
• For dual-wield Akali, Sasori, or compact Naruto builds, see the shorter-handled Akali Shadow Kama, Sasori Compact Anime Kama, and Hand-Forged Anime Combat Kama.
