It is a slightly larger size than Funayuki.
You can easily sell fish that are a little larger than the 15cm boat.

It's thinner and lighter than regular Deba, so it's perfect for those who feel that Deba is a little big.

Long ago, when fishermen went fishing, they could not carry many tools with them, so they started carrying just one versatile and convenient knife.

It is a knife that has evolved into a versatile knife for fish dishes, so much so that many people say that it is easier to cut three pieces or small fish than Deba, and like the Santoku knife, it is a very convenient knife that can be used for meat, fish, and vegetables. It's a book.


Indigo knife, boat 16.5cm

"Craftsman collaboration" combines different craftsmanship techniques from different production areas.
This is a collaboration product between Osaka's Sakai cutlery, which boasts a history of 600 years, and Tokushima's indigo dyeing.

The base wood is Hiba wood, which is top class in rot resistance.
We applied indigo dyeing, which has been valued since ancient times for its antibacterial, deodorizing, and insect repellent effects.

After dyeing the wood, we sprayed it with indigo dye to create a gradation.
A product that combines functionality and visuals has been created.

Ai Knife is an initiative to ``generate profits for multiple production areas with one product.''
Please try once.

[Option] About the special case (sheath)

Option price: 10,000 yen (12,000 yen for Yanagi blade)

This is a sheath exclusively for the Ai knife. The scabbard is also dyed with indigo. If you have the opportunity to carry a knife, please consider this.

The material of the sheath is "Honoki".

*We prepare sheaths according to the type and length of the blade.

*It may not fit knives other than Ai knives.

*After purchase, we cannot accept returns or refunds for reasons such as the size of the knife does not match your own knife, which is not an Ai knife.

[Optional] About Tosa Washi gift wrapping

Option price: 500 yen

We also offer gift wrapping using Tosa washi paper as an option. Please use it as a present for your loved ones.

You can also add a gift (5 yen coin) as an option. We recommend this as it is a typical Japanese way of giving a gift that conveys the wish that your relationship will last forever.

Since ancient times in Japan, there has been a culture of giving knives at celebratory occasions as a gift to ward off evil and misfortune and bring good fortune. Please continue to use it to "open up" a bright future.

Thoughts on Ai knives

There is a reason why I decided to create a knife with a new concept called the Ai knife.

I wanted to make Japanese knives more hygienic, and I wanted to stimulate the manufacturing industry and craftsmen by creating new value.

In order to create value that is unaffected by time and culture, we decided to develop products centered on functionality and people.

When it comes to tools, functionality is more important than design. It involves people, not machines. I thought that something that is spontaneous and unique to humans, and in a sense resembles folk art, would resonate with the hearts of those of us who are tired of mass production and mass consumption. Possibilities created by craftsmen who would otherwise never have met.

We hope that the value of collaboration with artisans can be conveyed to everyone through the Ai knife!
