Three Major Knife Regions in Japan

  • We are excited to introduce you to Japan's three major knife-producing areas. Our goal is for you to experience the exceptional performance and traditional craftsmanship of Japanese knives, deepening your trust and affection for them.

  • All the knives we handle are made in Sakai. This is because 98% of Japanese chefs use knives from Sakai.

  • Sakai City in Osaka Prefecture, Sanjo City in Niigata Prefecture, and Seki City in Gifu Prefecture are renowned as the three major cutlery production centers in Japan. Sakai City, in particular, accounts for more than 90% of the market share in kitchen knives for professional chefs in Japan, with knives meticulously crafted by hand by skilled artisans. Sakai City is also known for the development of single-edged blades and the roots of the Deba (protruding blade).

  • In contrast, Seki and Sanjo are known for producing double-edged knives, which are commonly used in households. On the other hand, Sakai excels in crafting single-edged knives, which are highly regarded for their sharper cutting edge.

  • 1. Sakai City

  • Sakai City is renowned as a leading production area for Japanese knives, where many craftsmen continue to create high-quality knives using traditional techniques. This passion and dedication have earned Sakai City's knives high praise from professional chefs globally. In fact, it is said that over 98% of professional chefs use Sakai City’s Japanese knives, reflecting their exceptional sharpness and ease of use.

  • Sakai City's knives are also favored in high-end restaurants and cooking schools worldwide, further enhancing their reputation for outstanding quality.

  • 1-1. Features of Sakai's Japanese Knives

  • In Sakai City, the process of making knives is clearly divided into three stages: "Forging," "Sharpening," and "Handle Attachment," each carried out by specialized craftsmen. This division of labor is deeply rooted in the history of Sakai's cutlery industry. Originally, it was introduced to ensure parts compatibility during firearm manufacturing. This approach, which prioritizes specialization and efficiency, has also been applied to knife making.

  • Of course, there are other regions that have adopted a similar division of labor, while some places integrate forging and sharpening into a single process. There are also regions outside Sakai where blacksmithing is specialized, often referred to as "local blacksmith groups," which mainly produce agricultural tools and vegetable knives. This distinguishes them significantly from the professional-grade knives made in Sakai.

  • Sakai knives are made entirely by hand, requiring the skill of craftsmen, and this expertise has been passed down for generations. What makes Sakai knives special is this division of labor and the high level of skill involved. Sakai knives require fine adjustments that are difficult to achieve with machines, which is why they are highly regarded by professional chefs. On the other hand, due to their lower production efficiency, Sakai knives sometimes lose market share to other regions for household knives. Nonetheless, the craftsmanship and appeal of Sakai knives remain undiminished.

(1) Forging

The blade material is heated in a furnace and shaped with a hammer. The process involves over 10 steps, with the blade material being heated in a high-temperature furnace each time, hammered repeatedly, and forged. Finally, the "ji" (base) is finished into the desired shape of the knife.

(2) Sharpening

Multiple sharpening stones are used to sharpen the blade and bring it to a cutting state. Depending on the type of knife, more than 10 different sharpening stones may be used for various purposes. This process is called "Hatsuke" or sharpening.

handle_attachment

(3) Handle Attachment

This is the process of attaching a handle to the sharpened blade. The part inserted into the handle is heated, inserted into the handle, and the distortion is corrected. By making final adjustments to any imperceptible distortions, a high-quality knife with prolonged sharpness is achieved.

  • The secret to Sakai knives' high quality and superior sharpness lies in the advanced skills of craftsmen in various fields, which have been passed down for many years.

  • 1-2. The History of Sakai Cutlery

  • Sakai City is renowned for having Nintoku-ryo Tumulus, the largest ancient tomb in Japan. It is considered one of the world's three largest tombs, along with the Great Pyramid of Giza in Egypt and the Mausoleum of the First Qin Emperor in China. The origin of Sakai forged knives dates back to the 5th century, during the construction of the Nintoku Tumulus, when many blacksmiths gathered to create tools.

  • Sakai City developed as a major transportation hub, where many roads intersected, making it a place where people and goods could easily gather. Facing the Seto Inland Sea, it also thrived as a trading port. A wealth of information, technology, and foreign cultures flowed into Japan, and in 1543, the Portuguese introduced guns and tobacco to Sakai. This led the blacksmith groups, who were making tools necessary for tomb construction, to start producing tobacco knives for cutting gunpowder and tobacco leaves.

  • Especially notable were the tobacco knives stamped with the mark "Sakai Kiwami," monopolized by the Tokugawa shogunate. Consequently, the name of Sakai and the high quality of the knives produced there became widely known throughout Japan, with the Deba knife, originating from Sakai, becoming particularly famous and sought after by chefs nationwide. The quality of these knives was recognized, and as a result, Sakai knives gained prominence across the country.

  • Currently, like many traditional industries, Sakai is suffering from a shortage of skilled labor. As a result, production scale continues to shrink. Nevertheless, the division of labor, which is the identity of "Sakai Forged Knives," is maintained, and skilled craftsmen specializing in forging, sharpening, and handle attaching continue to strive for excellence. This ensures that Sakai maintains a significant position in the high-end professional knife market. The proximity to Osaka, once called the nation's kitchen, also contributed to the development of Sakai knives, supporting culinary culture. Due to their high quality and craftsmanship, Sakai knives continue to be loved by many chefs.

  • The history of Sakai City's Japanese knives is a rich cultural heritage that has evolved alongside the development of the region. Long-standing traditions will continue to be preserved for the future, ensuring that Sakai forged knives remain a symbol of quality and craftsmanship.

The Origin of Craftsmanship

  • The Art of Collaboration: The Legacy Behind Sakai Knives

    The tradition of making Sakai knives is rooted in a unique approach that has been passed down through generations: collaboration through division of labor. Blacksmiths, blade sharpeners, and distributors—each focuses on their expertise, honing their craft to create knives of the highest quality.

  • Rather than one craftsman handling every step, each specialist refines their part of the process. Blacksmiths dedicate themselves to forging the steel, blade sharpeners perfect the edge, and distributors ensure these exceptional knives reach the hands of users. This synergy is what gives Sakai knives their world-renowned excellence.

  • Division of labor is not just about splitting tasks; it’s about trust and mutual support. Knowing that the knife I forge will be further elevated in the next stage inspires a sense of responsibility and fuels my desire to create something truly exceptional.

  • The legacy of Sakai knives thrives because of this collaborative spirit, where each step is an act of dedication and respect for the craft. Every knife we produce carries the collective passion and skill of many artisans. Today, we continue this tradition, pouring our hearts into every blade, ensuring that the legacy of Sakai lives on for generations to come.
