![Chiba Koshogu Hand-Forged Grass Sickle (Kama): Where to Buy [2026]](https://jpmono.com/wp-content/uploads/2026/05/japan-map-regions-and-prefectures-800x1050.png)
On the flat, sandy farm belt east of Tokyo, village blacksmiths have been forging sickles, hoes, and knives for the people who work the land for centuries. The piece covered here is one of those tools brought into the present: a kusakari-gama (草刈鎌, “grass-cutting sickle”) made by Chiba Koshogu (千葉工匠具) smiths on the Kujukuri plain. Per the spec for this guide, it is a hand-forged, single-bevel grass sickle with a high-carbon steel edge forge-welded onto a softer iron body — the same lamination logic used in Japanese kitchen and garden blades.
What makes Chiba Koshogu notable internationally is recognition, not romance. In 2017 Japan’s Ministry of Economy, Trade and Industry (METI) designated Chiba Koshogu a national traditional craft — Chiba Prefecture’s second such designation, alongside the Boshu Uchiwa fan. That places a humble farm sickle in the same legal-heritage category as lacquerware and porcelain, on the strength of a defined process: free-forging by hand, forge-welding hard steel to soft iron, and water quenching for a keen, re-sharpenable edge.
This article is for gardeners, small-acreage growers, and tool enthusiasts outside Japan who are weighing a genuine maker-forged sickle against a hardware-store stamping. It explains the hand-forged carbon-steel edge, the care it demands, and how this kind of Japanese tool compares with other forged tools. Details that vary by maker are identified rather than guessed.

Who this is for — and who should skip it
- Want a maker-forged, re-sharpenable blade rather than a disposable stamped sickle
- Do regular hand weeding, verge trimming, or small-plot harvesting
- Already maintain carbon-steel tools and are comfortable with rust care
- Value a defined craft process (METI-designated) and traceable origin
- Are buying for someone who appreciates Japanese hand tools
- Want a zero-maintenance, dishwasher-and-forget stainless tool
- Need to cut woody brush, saplings, or thick stems (this is for grass and weeds)
- Are left-handed and need a confirmed left-bevel option
- Need a guaranteed delivered price before ordering (none is stated here)
- Expect a long-handled scythe — this is a short, one-hand sickle

📍 Where this comes from — place, era, and the craft tradition
Chiba Prefecture is the broad peninsula that forms the eastern wall of Tokyo Bay, immediately across the water from the capital. The forges that make this sickle cluster in Togane and Sanmu, on the inland edge of the Kujukuri plain (九十九里平野) — a long, flat, sandy coastal lowland running down Chiba’s Pacific side. In the old provincial map this was Kazusa and Shimōsa, and the plain was for centuries one of the largest single stretches of agricultural land in Japan.
That geography is the whole reason a blacksmith tradition took root here. Flat, workable farmland at scale means constant demand for the tools that work it: sickles to cut grass and harvest, hoes to turn soil, knives and shears for everything in between. Where the fields are, the smiths follow.
- Late 1500s — The warring (Sengoku) era ends; some swordsmith lineages turn to forging farm implements as demand for weapons falls.
- Edo period (1603–1868) — The Kujukuri plain develops as a major farm belt in Kazusa/Shimōsa; village smiths supply sickles, hoes, knives, and shears.
- 18th–19th c. — Sustained demand for farm implements keeps the local forging trade alive across generations.
- Meiji onward (1868–) — Hand free-forging persists alongside industrial tool-making.
- 2017 — METI designates Chiba Koshogu a national traditional craft — Chiba’s second, alongside Boshu Uchiwa.
- 2026 — The kusakari-gama is still hand-forged one at a time in the Togane / Sanmu forges.
The historical hook here is not a former capital but a craft lineage. According to the data notes for this guide, some of the village smiths descended from swordsmith families who, once the warring era closed, redirected their forge skills from weapons to the implements a farming economy actually needed. The technique carried over: forge-weld a hard, high-carbon steel edge onto a softer, more forgiving iron body, then water-quench it. That lamination is exactly what gives a sickle a thin, keen edge that can be re-sharpened many times rather than thrown away when dull.
The METI designation in 2017 is the formal recognition of that continuity. It is worth noting what it certifies: not a single famous workshop, but a defined regional process — hand free-forging (火造り), forge-welded steel-on-iron lamination, and water quenching (焼入れ) — kept alive by the smiths of the district.
“A grass sickle is the most ordinary tool on a farm — which is exactly why it took a few hundred years of daily demand on one wide plain to forge it this well.”
What “still being made here” means in practice: the kusakari-gama remains a hand-forged object, shaped one at a time rather than stamped from sheet. The exact number of active forges and succession picture is not detailed in the spec for this guide, so we will not put a figure on it — but the 2017 national designation indicates a tradition judged to be living, not archival.

What it does well
Weaknesses and things to verify before buying
- Carbon steel rusts. The high-carbon edge will spot and patina if left wet. It needs wiping dry and a light oil after use — not a set-and-forget stainless tool.
- Grass and weeds, not woody brush. A thin single-bevel grass sickle is for soft growth and harvesting; using it on saplings, thick stems, or wire risks chipping the edge.
- Confirm the current total and fit before ordering. Allow for any shipping or forwarding fees.
- Handedness. Single-bevel blades are handed. The standard is right-bevel; left-handed buyers must confirm a left option exists, which is not stated here.
- Sharpened blade import rules. Some countries restrict or tax imported bladed tools. Check your local customs and any age-of-buyer rules before ordering.
- Sharpening skill required. Getting full value means maintaining a single-bevel edge on a whetstone; buyers expecting a pull-through sharpener may be frustrated.
