Many users do not fully understand the properties and functions of knife materials. In fact, any material has advantages and disadvantages, and it is impossible to cover everything. Some materials have good wear resistance, but poor toughness; some materials have good toughness, but have poor wear resistance. Generally speaking, most knives cannot be used because of following two reasons: one is wearing out, which is closely related to the wear resistance of the material; the other is crack, which is closely related to the toughness of the material. So users must choose the material of the knife according to their own special needs. Figure 1 is a comparison chart of the wear resistance and toughness of some typical knife materials. Their performance and prices are also very different. Figure 2 is a comparison chart of their service life.
