In the complex world of knife making, steel selection plays a critical role in determining a knife's quality, durability and overall performance. Among the many materials available to manufacturers, D2 steel, which stands out especially with its hardness and durability, has an important place.

A knife's hardness is vital to its sharpness, durability and wear resistance. D2 steel is known for its high hardness level, usually ranging from 55 to 62 HRC (Rockwell Hardness Scale), making it an important member of the tool steel family. This high hardness ensures that D2 steel blades offer exceptional resistance to wear and tear, as they are defined by their high carbon and chromium content.

However, this high hardness of D2 steel means that sharpening the knife will require more effort and the right tools. But this effort pays off by ensuring that the knife stays sharp for a long time. Therefore, D2 steel knives are quite popular among enthusiasts and professionals looking for sharpness and durability.
