Hori-Hori

Also known as: Japanese gardening knife, soil knife, weeding knife

A traditional Japanese gardening tool — a heavy carbon-steel blade roughly 7 inches long, sharp on one edge, serrated on the other, with a concave profile that holds soil like a narrow trowel. The single most-versatile hand tool in a working gardener's belt: weeds, transplants, divides, cuts roots, opens furrows, removes invasive runners, prys rocks, harvests root crops, and scoops compost. The name (掘り掘り) translates loosely to 'dig dig.'

The hori-hori is the working gardener’s general-purpose blade. A single tool that handles a startling fraction of routine garden tasks better than the dedicated tools meant for each. The Japanese landscape tradition has used it for centuries; modern Western gardeners adopting it consistently report putting away two-thirds of their other small tools.

What it does

Weeding — the sharp edge cuts roots; the narrow concave blade slides under taproot weeds (dandelion, dock, plantain) and levers them out
Transplanting — the blade is shaped like a narrow trowel; works in tight spaces a regular trowel doesn’t fit
Dividing perennials — slice through clumps; saw apart root masses with the serrated edge
Harvest — root crops (carrots, beets); slicing herb bunches; cutting leaf lettuce at base
Opening furrows — a quick line along the bed surface
Bulb planting — concave profile holds a small bulb in place while opening the hole
Prying — small rocks, root pieces, stuck plant ties
Measuring — many hori-hori blades are marked in inches/cm for planting depth reference

Anatomy

Blade: ~7 inches (180mm) of carbon steel, slightly concave (scoop-shaped), pointed tip
Edges: one sharpened smooth, one serrated
Handle: typically wood (often oak or magnolia) with a brass ferrule; some modern versions have plastic or rubber handles
Sheath: traditional leather or modern nylon — important; the tool is sharp enough to cut through pockets

Choosing one

Three tiers:

Forged Japanese carbon steel (Nisaku, Hida, Suncraft) — $40–$80; will last decades with care; takes a sharp edge
Stamped stainless mass-market versions — $15–$30; usable but the steel dulls quickly and the edges are softer
Garden-store generic — variable quality; the cheap end of this category is not worth carrying

The traditional carbon-steel blades develop a patina (and some surface rust if neglected); a light oil after use keeps them serviceable for generations.

A note on safety

The hori-hori is a knife. Carry it in its sheath when not in use. Cut away from your body. Sharpen carefully — the serrated edge in particular catches if mishandled.
