K390 is a premium powder metallurgy tool steel produced by Bohler-Uddeholm. Designed originally for industrial cutting applications, it offers extremely high wear resistance and excellent edge retention due to its high carbon and vanadium content. Unlike stainless steels, K390 has lower corrosion resistance and requires regular maintenance to prevent rust. However, its combination of toughness and cutting performance makes it highly respected among knife enthusiasts seeking maximum cutting efficiency and durability.
