Folding pattern steel/Damascus steel in China

Folding pattern steel is a type of steel that has been processed through a series of folding and forging techniques to create a pattern on the surface of the metal. This pattern is usually made up of a series of waves or ripples that are created by folding the steel repeatedly in different directions.

The process of creating folding pattern steel involves heating the steel to a high temperature and then hammering or pressing it to create the desired shape and pattern. The steel is then cooled and polished to create a smooth, even surface.

Folding pattern steel is prized for its beauty and durability, and it is often used in the production of high-quality swords, knives, and other edged weapons. It is also used in the manufacture of decorative items, such as jewelry and vases, and in the construction of buildings and other structures.

Damascus steel is a type of steel that is known for its distinctive pattern of swirling, wavy lines on the surface of the metal. It was originally produced in the city of Damascus, Syria, in the Middle East, but it was also made in other parts of the world, including India, Japan, and China.

In China, Damascus steel was known as "jinsu," or "gold wire steel," due to its golden-colored pattern. It was made using a similar process to that used in the Middle East, involving heating and forging the steel repeatedly to create the desired pattern.

Damascus steel was highly prized for its strength and beauty, and it was used to make a variety of edged weapons, including swords, knives, and daggers. It was also used in the production of decorative items, such as jewelry and vases. Today, Damascus steel is still prized for its beauty and is often used in the production of high-quality knives and other edged weapons.
