Forging Technology

The History of Forging

Forging is a process of preparing iron by beating until a certain shape is created. The Chinese character 鍛 means to forge an object until it is strong and resilient. Before 4000B.C. in Egypt and Mesopotamia, people forged copper, gold, and silver to make ornaments, objects of worship, and weapons.

The ancient forging technology developed for hundreds of years. The forging technology for weapons evolved, as well as for household commodities and farming tools such as hoes and axes.

Around 470 A.D., materials brought from the mainland china were introduced, strongly influencing the current technology. As a consequence, diverse tools proliferated since the introduction of these eccentric materials. Around 500 A.D, the production of iron in Chugoku, San-in, Kita Kyushu and Tohoku regions began. This led to the spread of carpenter tools, hunting equipment, horse riding harnesses, and body armor used in war.

Towards the end of the Heian Era, Japanese sword craftsmanship reached to the level of profound perfection. The Japanese swordsmith boasted unparalleled sharpness. This forging technology went on its skill to create to become a renowned and cultivated historical tradition.

Melting iron and pouring it into shape is universally known as casting. It is relatively easy to make iron sheets and other complex shapes; however, the drawback is that they crack easily.

Where does the strength come from in forging? Japanese swords or well-sharpened kitchen knives are not forged by means of melting. They are beaten by a hammer and manufactured so that the desired shapes are made. It is a time consuming process, and, it is sometimes rather difficult to attain the desired shape. Nevertheless, the strength lies in the impeccable sturdiness of a product that does not break easily.
The unyielding metal is produced by steady forging throughout production.

Our forging method might take long time, but we believe it is very important that we produce products of high quality. When we say “high-quality products” we are not just saying that—we really mean it. Nonetheless, in surprising contrast to the deficit of our way of forging, one of our strengths is the speed—We have solved the paradox through hard work, practice, and search for perfection for decades. As a result, we could achieve cost efficient way of production and thus meet and exceed clients’ expectations.
