Spyderco K390 Line
Bohler K390 is a cold work tool steel made with 3rd Generation particle metallurgy processing specifically developed to provide the extreme wear resistance and high compressive strength needed in industrial cutting, blanking, and punching operations. K390 is exceptionally tough and free of impurities compared to conventional steels with CPM-10V-level edge retention and increased toughness. As a tool steel K390 is not stainless and requires consideration to prevent corrosion. K390 is available in a number of Spyderco knives including the Ladybug 3, Manbug, Dragonfly 2, Delica 4, Endura 4, Endela and Police 4 lightweight FRN models.
