Nisaku

The Tomita mark

Nisaku tools are forged and ground by Tomita Cutlery, a Japanese blade maker established in 1960, from stainless steel that resists rust and scratches. Each hori hori knife, nejiri gama and crack weeder keeps the traditional Japanese pattern and adds modern precision: a sharp edge that holds, a handle that fits, and markings where you need them.

I Was Wrong - More Than Worth It

I was really skeptical about buying this but it was $5 so I figured why not ? When I got it, I was even more skeptical, it was small and seemed so flimsy. I thought for sure that using it against pavement would snap it in a heart beat. I WAS WRONG ! I have a motorcycle pad made with pavers, so I get the occasional weed growing around the edges.

This makes weeding actually enjoyable!

After the snow melted and rain finally stopped, I found my flower bed and vegetable garden full of thistles and dandelions that have grown to significant sizes. I was looking for an organic way to remove them & luckily came to learn about a tool called Hori Hori Knife. After doing a quick research on the internet, I've learned Nisaku is a producer of the best quality Hori Hori Knife.

Awesome tool

Terrific tool for weeding and planting. Very sharp edge - cut right through roots and soil.

Surprisingly effective

I’ve tried using trowels and pressure washers, and this thing beats them all. Hands down. I think the corrugation is the key. It makes quick work of severing or dislodging the greenery that insists in growing in my driveway and pool deck cracks/crevices/seams. I’m really impressed with how quick and easy that was. It showed up this afternoon, and I had all my cracks cleared, front and back, in about 10-15 minutes.

Perfect tool for the garden bag

I used this recently to spread manure. It helped me pierce the bag and cut it open. Easy enough my son helped. The sheath it great because it needs a place to call home. The blade looks the same as the day we bought it so I think it will last, and with the serrated style edges, it’s versatile too.

This tool makes a job that was tedious and messy, easy and quick.

I bought this after trying all the other models which are well made and sufficient - I even bough a few of them to give to friends. I mostly bought this one to have so that I can be comfortable lending it out. Usage note: if your sidewalks are old and the joints are rough or un-even this will still do the job. Do not use force. Pressing harder will work less well on uneven joints.

Why choose Nisaku gardening tools?

One knife, many jobs

Customers who purchase a Nisaku hori hori knife usually find it becomes the most reliable tool in the garden bag. It digs planting holes, divides flower clumps, cuts roots and twine, and the inch markings show bulb depth. The design began with the Matagi hunters of Japan; the company that makes it today, Tomita, has kept that tradition since 1960 and added modern precision.

Craftsmanship you can feel

Every blade is ground from stainless steel for rust resistance and durability, and the special editions are hardened to HRC58. The result is a versatile, sharp edge designed for years of work: a blend of craftsmanship and innovation that gives an exceptional experience in the hand, season after season.

Next to the hori hang the nejiri gama hand hoe, claw cultivators, crack weeders, sickles, scrapers and kitchen knives. Pick the tool for the job, give it a little care, and it will stay on its peg for good.

Asked over the fence

What is a hori hori knife used for?

A hori hori knife is a Japanese digging knife. Gardeners use it to dig planting holes, transplant bulbs and seedlings, divide perennials, cut roots and twine, and lift weeds with long tap roots. The inch markings on a Nisaku blade show planting depth.

Which Nisaku hori hori knife is the best quality?

The NJP650 is the original and the most popular. If you work rocky or rooty soil, the NJP651 and NJP801 are hardened to HRC58 and hold an edge longer. The No. 6550 full tang and the No. 6800 full metal versions are the strongest builds.

Are Nisaku tools made in Japan?

Yes. Nisaku tools are made in Japan by Tomita Cutlery, established in 1960, from Japanese stainless steel. In the United States they are distributed by Snow Joe + Sun Joe.

What is a Japanese weeder?

Japanese weeders are hand tools with a thin, sharp blade that cuts weeds at or just under the soil line. The best known is the nejiri gama, a hand hoe with an angled blade used with a pulling stroke. Crack weeders with corrugated blades are made for sidewalks and pavers.

Is a hori hori considered a weapon?

A hori hori is a gardening tool. Carry it in its sheath, keep it in the garden bag or on the peg wall, and check local rules if you plan to carry any fixed blade in public.

How do I keep a stainless steel blade sharp?

Clean and dry the blade after each use, and touch up the edge with a fine whetstone or diamond file a few strokes at a time. Serrated edges are sharpened tooth by tooth with a tapered rod.

Still deciding which peg to fill?

Start with the knife that started it all, then add a hand hoe and a crack weeder. Most gardens need no more.
