Sumida, Tokyo and Sakai, Osaka, March 14, 2023 - As a Japanese company headquartered in Tokyo, Redhorse Corporation are dedicated to projects aimed at regional development throughout Japan, including consulting on local products, promoting tourism, and facilitating inbound travel. Our mission is to share the beauty of Japan and ensure its sustainability for generations to come. 

With a remarkable 600-year history, the Sakai knife industry stands as a beacon of tradition and excellence in blade craftsmanship. Sakai city, renowned for its centuries-old tradition of blade crafting, has seen its once-flourishing industry facing challenges in recent times. This Kickstarter campaign, initiated by passionate artisans and advocates of Japanese heritage, seeks to breathe new life into this esteemed craft while honoring its rich legacy and aims to showcase the unparalleled craftsmanship of Japanese knives to the world. 

Today, Japanese craftsmanship is renowned worldwide across various industries for its exceptional quality. This reputation stems from the meticulous craftsmanship and dedication to manufacturing passed down through generations. The product we are launching is the “Sakai Kitchen Knife” from Sakai City, Osaka, which embodies this meticulous craftsmanship. Holding over 90% share in the professional chef knife sector (https://osaka info.jp/special/sakai/), our mission is to share the legacy of these Sakai Bladesmiths with the world and provide support to the artisans who have dedicated their lives to this craft.  

Currently, there is a pressing issue concerning the succession of the craftsmanship, as there is a severe shortage of successors. This stems from both the aging of business owners and craftsmen, as well as a lack of new labor entering the field. To ensure the continuation of the invaluable craftsmanship and history of Sakai Uchihamono, it is imperative to train young artisans. 

We will showcase four original Sakai Uchihamono (打刃物, hand-forged knives) developed using this time-honored craftsmanship, marking their debut on the global stage. 

In 1982, Sakai Uchihamono was officially recognized as a ‘traditional craft’ by the Minister of  Economy, Trade, and Industry (https://www.city.sakai.lg.jp/kanko/sakai/keisho/dentosangyo/sakaiuchihamono.html). Its quality is not only acknowledged in Japan, but also globally. 

As individuals engaged in regional development projects across Japan, we aim to utilize this crowdfunding campaign to gather support from individuals worldwide who value quality. Our  goal is to preserve this traditional industry and impart the artistry of Sakai kitchen knives to  the next generation. 

We have created four unique knives for the Kickstarter campaign.

Three Key Features 

①Kuro-uchi Kitchen Knives

Kuro-uchi kitchen knives feature the deep, rich appearance inherent to iron. We’ve crafted these knives with a focus on design, imbuing them with a rugged, handcrafted feel that exudes a sense of capability and presence. The black rust formed during quenching adds a unique beauty to the knife,  while its original state stabilizes the iron and prevents rusting. Resistant to wear and tear, these knives offer long lasting performance. 

②Octagonal Handle 

Balance is paramount in Japanese kitchen knives, so we’ve opted for an octagonal handle that is lightweight, durable, and ergonomically designed for a comfortable, non-slip grip. We’ve prioritized ease of use and grip comfort with this design. The octagonal handle provides a secure grip and prevents slipping during use.

③Handcrafted by Specialized Artisans 

Each of our knives is meticulously handcrafted by master artisans certified as traditional craftsmen, each specializing in their respective fields. With utmost care and attention to detail, these skilled craftsmen produce the proud kitchen knives of Sakai Toji. 

History of Sakai Uchihamono 

Sakai perforated cutlery boasts a history spanning 600 years, tracing its roots back to the 5th  century. The origins of Sakai cutlery can be traced back to the 5th century, when blacksmiths  in Sakai were assembled to create tools necessary for constructing the renowned tombs of  Emperor Nintoku and other emperors in the region. 

Centuries later, during the latter half of the 16th century, tobacco was introduced to Japan  from Portugal. This led to the need for knives capable of cutting tobacco leaves, prompting  the production of tobacco knives in Sakai. Recognizing their sharpness, the Tokugawa  Shogunate bestowed upon them the prestigious “Sakai Kiwame” seal, and they were  exclusively sold across Japan under this seal. It’s said that the reputation of Sakai cutlery  spread throughout Japan following its recognition by the Tokugawa Shogunate.

≪Message from Izumi Cutlery Works Representative Handling this Product≫

This is our international debut and through this project we sincerely hope that the true  appeal and values of Japanese knives will be put into the hands of people all over the world.  We have produced our products by paying attention to every single step of the process and  employing first-class traditional craftsmen. In the future, we hope to continue to offer products that will further satisfy everyone. 

≪Project Manager Message≫ 

Having spent my school years in an environment rich in international exchange, I’ve always  taken pride in the beautiful culture and traditions of my native Japan, which allure people  from all corners of the globe. I harbor a strong desire to make these aspects more widely  recognized among both the Japanese populace and the global community. I am overjoyed that  my dream has materialized, allowing me to introduce Sakai Uchihamono, a traditional craft  hailing from Osaka—my hometown—to the world.  During the preparation for this project, I’ve uncovered many charms of Osaka and Japan,  some of which were previously unknown to me, despite being an Osaka native. I am thrilled at  the prospect of sharing these enchantments with people worldwide.  We remain dedicated to ensuring the satisfaction of all parties involved in this venture,  including the artisans of Sakai Cutlery, the global audience purchasing the knives, and the  local community.
