What is the strongest type of Steel for a samurai sword?

The material of cold steel is very good. In addition to being very expensive, cold steel has both hardness and toughness. It is a more common but good quality choice. The manganese steel knife has good toughness, but the hardness is relatively low, but the price will be cheaper, the cut is easy to maintain, and it is not easy to damage. Carbon steel knives are relatively sharp and have low toughness, but they have a good shape and can make that kind of handsome knives. It is a good choice for simple decoration. You can choose according to your purpose, thank you.
