Niwaki Hori-Hori Pro
"The Japanese-forged digging knife that replaces a trowel, a soil knife, a weeder, and half a hand pruner — in one tool. The Pro version is the upgrade pick over the standard Hori-Hori."

Anyone who has ever wished their trowel was sharper, their soil knife stronger, or their hand pruner deeper-reaching. Especially: gardeners who divide perennials, plant from plugs, edge beds, or work in stony or compacted ground. After one season you will reach for it more than your trowel.
Container-only gardeners (overkill for potting). Anyone unwilling to wipe and oil a high-carbon steel blade after wet work (it will rust visibly within a few weeks if neglected). First-time hand-tool buyers — start with a basic stainless trowel for a season to understand what you need.
/ what we love
- One tool replaces four: trowel, soil knife, weeder, root splitter. The single most space-efficient piece of gardening equipment in our coverage.
- Drawn high-carbon steel from a centuries-old Japanese smithing tradition. The edge geometry is markedly sharper than Western trowels and holds across far more uses.
- FSC-certified beech handle, brass ferrule, canvas sheath included — the build quality matches the blade.
- The signature red sheath trim is unmissable in the compost heap, the lawn, the wheelbarrow. Niwaki's most quietly practical design choice.
/ what to know
- High-carbon steel rusts visibly within weeks if left wet. Wipe and oil with camellia oil after every use — non-negotiable.
- The Pro is heavier than the standard Hori-Hori (the longer blade adds mass); if your wrist is small, try the standard first.
- Niwaki's parts library is smaller than European brands like Felco; order spare blades at time of purchase rather than years later.
Why a hori-hori, and why the Pro
“Hori-hori” is the sound of digging in Japanese earth — onomatopoeia turned tool name. The classical hori-hori has been used by Japanese gardeners for centuries: one side concave for digging, the other serrated for cutting roots, the spine sharpened for splitting bulbs. Western gardeners have steadily adopted it over the past twenty years as the most space-efficient hand tool in the working library.
The Niwaki Pro is the upgrade tier above their standard Hori-Hori. The differences that matter:
- SK-5 carbon steel (vs. the lower-grade steel in budget Japanese-style copies)
- FSC-certified beech handle with brass ferrule (vs. plastic or cheap hardwood)
- Longer 180 mm blade for deeper digging and root-divider work
- Canvas sheath included (the budget versions ship bare)
For gardeners who have used a basic hori-hori for a season and want the upgrade — or for first-time buyers who’d rather buy once — this is the right tier.
Where it sits in our framework
The Niwaki Hori-Hori Pro passes our four-question durability framework:
- Forged or stamped? Forged drawn carbon steel.
- Replaceable parts? Replacement blades and sheaths available through Niwaki direct.
- Real warranty? Manufacturer warranty against defects, honoured through Niwaki’s direct customer service.
- Manufacturer continuity? Niwaki has been in business since 2007, sourcing from Hyogo blacksmiths with multi-generational continuity.
Four yeses.
Care matters more than usual
This is a high-carbon-steel tool. Unlike stainless trowels, it will rust if left wet. The care routine takes ninety seconds:
- Wipe the blade with a dry cloth after every use
- After wet work, dab a thin film of camellia oil (around $14 for a bottle that lasts five years) on both blade faces and the spine
- Store in the canvas sheath
- Twice a year: a 60-second touch on the bevel with a Niwaki crean mate or any 600-grit diamond stone
Treat it this way and it will outlast you.
