One knife. Many hands.

At Tadafusa, knife making is a team effort shared by around 30 craftsmen.

Our knives are not made by a single craftsman from start to finish. Instead, each craftsman specializes in a particular process—such as forging, sharpening, or handle polishing.

By dedicating themselves to a single process, they can continue refining their skills over many years.

Each process is supported by experienced craftsmen who help newer craftsmen develop their skills. And when challenges arise, everyone works together to keep things moving.

The next time you hold one of our knives, remember—every knife is the work of many hands.

Planning a visit to our shop this summer?

Some visitors choose to walk from the nearest station. Our "nearest" station is still about a 30-minute walk away! We're always grateful to those who make the walk.

If you're visiting us this summer, please stay hydrated and travel in whatever way is most comfortable for you. Your health comes first.

We're usually open Monday to Saturday, but we'll be closed on July 24 (Fri) and July 25 (Sat) for staff training.

If you're visiting Sanjo during those two days, why not stop by ? Their hands-on blacksmithing experience might just become a highlight of your trip to Japan.

Why is our tiger smiling?

It all starts with our founder, Torasaburo Sone.

After graduating from elementary school, he began his apprenticeship as a kanejaku (Japanese carpenter's square) craftsman. At the age of 34, he founded Tadafusa in 1948.

With no one to teach him knife making, he studied, experimented, and developed his techniques on his own. He devoted himself completely to his craft, laying the foundation of Tadafusa through years of hard work.

People who knew him often said they rarely saw him smile.

So we let the tiger smile instead. Tora means "tiger" in Japanese, and that's how Smile Tiger was born.

Today, Smile Tiger still watches over our knife making, quietly reminding us of the founder whose passion continues to shape every knife we make.

No rush, no pressure.

Here, you can take all the time you need to compare our knives and choose at your own pace.

We know that stepping into a small shop can sometimes feel a bit intimidating. You might wonder if you’re expected to buy something.

Please know—there is no need to worry at all.

Pick up the knives. Feel their weight. See how they fit in your hand. And if you decide they’re not quite right for you, that is perfectly okay.

In fact, some of our visitors leave empty-handed. Others take their time to think it over and come back a second or third time.

Anyone with a curious mind or an interest in knives is always welcome here.

Of course, we’d love it if you find your perfect match right here in our shop. But a good knife is something you’ll live with for years.

More than anything, we simply hope you find the one that feels right for you—whether it is made by us or not.

Before our kitchen knives, there were these knives.

Knives for the fishing industry.

Over the years, we expanded from making knives for the fishing industry to harvesting knives, professional knives, and eventually kitchen knives for everyday use.

The techniques, knowledge, and experience gained through that work still live on in every knife we make today.

While kitchen knives are now our main focus, these knives are still made here today.

There’s a whole world of knives beyond the kitchen.

We'll be sharing more of the unique knives we've made since 1948.

Featured knife: Kakou Deba 210mm

“Is wanting a knife you can sharpen unusual now?”

A customer asked us this while looking for the perfect gift.
She’s been using her own Tadafusa knife for over 10 years, and wanted to share that same experience with a friend.

Our answer? You’re not alone at all.

The steel may vary from knife to knife, but every one of ours is made to be sharpened. And actually, many customers pick up a whetstone along with their new knife.

When they do, we can already imagine them caring for it for years to come—and honestly, nothing makes us happier.

But home sharpening isn’t the only way.
Choose the maintenance style that fits you best.
Your local shop offering resharpening services is always a great option.

What are the dramatic moments in knife making?
Forging? Quenching? Sharpening?

Absolutely.

But there’s a quiet step that can’t be skipped—

removing the bend.

After the major steps, the blade always bends a little.
Each time, we correct it one blade at a time, with a hammer chosen to match its thickness.

Thin blades—like yanagiba—bend easily and often, which makes this step especially delicate.

A tap on the steel reveals how differently each blade behaves.

The craftsmen work with each one as it is—guiding it toward its best edge.
