Steel 420J2

Steel 420J2

It is a low-carbon martensitic stainless steel used in the knife manufacturing industry. Because it has a low carbon content, this steel is relatively soft. The achievable hardness of 54 - 56 HRC does not meet the qualities that demanding customers expect from knives. On the other hand, it should be noted that knives with lower hardness are commonly available on the market. 

Usage of 420J2

This steel is one of the few soft stainless materials frequently used by knife makers. The low hardness is not a problem in the production of replica knives and weapons, as functional use is not anticipated in this field. We can find this type of steel in various folding knife designs. 

>In conclusion, 420J2 steel is widely represented among functional knives on the market. Therefore, we recommend that anyone looking for a functional knife carefully consider their purchase. The softness of the knife is unfortunately not the end of it. Knives made from such materials require frequent sharpening even after very light use.
