When it comes to shears, the ideal Rockwell hardness depends on the material being cut. Generally, a hardness of 55-60 is suitable for most hair types. However, for thicker and coarser hair, a higher Rockwell hardness of 62-65 is recommended to maintain sharpness and durability.
Liquid diamond, also known as carbon disulfide, is a unique substance that is both colorless and odorless. It is composed of carbon and sulfur atoms and is commonly used as a solvent in industrial processes. Despite its name, it does not actually turn into solid diamond when cooled down, but remains a liquid at all temperatures. Its unique properties make it an important component in many different applications, from rubber production to pharmaceuticals.
