The secret to the sharpness of Japanese blades.
Japanese blades have been developed through the constant pursuit of improved skills and efficiency, in order to make them the optimal tools for all kinds of situations. This is the result of finding the best materials, shapes, and manufacturing methods to suit various applications. The roots of these blades can be found in the Japanese swords that were used in warfare from the 12th to the 16th century.


Japanese swords needed the ability to cut well while not breaking in the battlefield. This led to the development of a forge welding technique by joining steel and iron to increase sharpness, and repeated heating and hammering to increase durability.


As Japan entered a relatively peaceful era in the 17th century, Japanese swords were valued more as works of art, and blades were developed in accordance with how they were used by craftsmen and the common people. There are currently many kinds of Japanese blades, ranging from craftsmen’s tools to kitchen knives, nail clippers, and other daily commodities.
Visiting famous blade production areas.
There are several famous blade production areas across the country. Let’s take a trip, looking for some of the blades that have been developed with their own unique features in their places of origin.

Seki, boasting the value in swords distributed in Japan, has been a famous production area of swords for over 780 years. One particularly famous swordsmith was Magoroku Kanemoto in the 16th century, who made many swords for influential warriors, which in turn granted Seki fame throughout the country. Today, many types of blades, including kitchen knives, are produced in Seki. A famous German blade manufacturer has even established a factory there for its line of finest blades. The Seki Kaji Denshokan Museum periodically gives demonstrations of traditional Japanese sword forging. The hall of blades also offers about two thousand and five hundred types of kitchen knives, scissors, and other types of blades for sale.
