How practical is the riffen patterned steel knife?

Ruifen patterned steel knife is very practical. Ruifen is a kind of patterned steel made by rapid sintering powder metallurgy technology, which belongs to Damascus steel in a broad sense. Because it is produced in Sweden, it is called Swedish powder steel for short. Swedish powder steel is a kind of stainless steel produced by powder metallurgy manufacturing process, which is a composite steel composed of more than two (usually two) steels. Delamination is completed in oxygen-free environment at the initial stage of pulverizing, and interlayer welding is consolidated by high temperature and high pressure process in oxygen-free environment. The precise proportion of powder of various elements first ensures its strong rust resistance, and then the smelting and manufacturing characteristics of powder steel can ensure the overall strength and interlayer strength to the greatest extent. Good practicability.
