We’re constantly finding new ways to become more sustainable, so we only select products that are built to last. We recommend that you use your weeding hoe correctly to extend its lifespan.

Use it correctly:

Japanese steel is hard and sharp, and can be more brittle than some people are used to - it will chip if abused
Do not cut wire, metal, stone, plastic or any other hard material (even bamboo fibres and some very hard woods, especially knots and burrs, can damage steel edges)
Do not twist or apply uneven pressure
Cut diagonally across branches (not straight across) so you cut along the fibres
Pay attention to our maximum cut dimensions, and don’t overdo it (shears are not loppers)
Use the base of the blades, not the tips, for heavier cuts

Keep it clean

Remove leaf resin, rust and gunk with a Crean Mate and water
Dry, wipe over with Camellia oil and store in a dry place

Highly recommended by traditional Japanese blacksmiths

Fantastic sharpening stones specially designed for Secateurs, but also great for Shears, Topiary Clippers and other sharp stuff.

The concave edge follows the curve of the blade perfectly, and they’re small enough to get into tight spots. These are what Tobisho recommend for their tools, and what Jake now uses for his secateurs.

Clean. Oil. Snip

Elevate your garden game: maintain like a master

Maintaining Niwaki tools is simple with the right care. After use, clean blades with Clean Mate, keep them lubricated with Camellia oil, and periodically sharpen using Niwaki sharpening stones. This routine ensures your shears, saws, and pruners stay precise, durable, and ready for effortless garden work season after season.

The perfect partner

Garden Tree

Niwaki means garden tree. Not very exciting, but it implies far more than that. Japanese gardens are landscapes, microcosms of nature, and the trees are all shaped to fit into those landscapes - there’s an awful lot of artistry and cultural heritage in there too.
