Spyderco Leafjumper Blue FRN K390 Blade

The Bohler K390 knife is a high-quality tool made from a special type of steel. This steel is created using advanced particle metallurgy processing, which gives it exceptional durability and strength. It is specifically designed for heavy-duty cutting, blanking, and punching tasks in industrial settings. The K390 steel offers outstanding edge retention, similar to other high-performance steels like 10V or S110V, while still maintaining good toughness. However, it is important to note that this knife has lower corrosion resistance, similar to the M4 steel.
