LadyBug3 - BLUE FRN / K390
This remarkable expression of the Ladybug is the first in a special series of Spyderco knives to supercharge the proven features of well-established models with this elite, high-performance steel. To make these K390-bladed knives even more unique, their injection-molded FRN handles will feature a distinctive blue handle color.
Manufactured by Böhler-Uddeholm, K390 is an advanced cold work tool steel produced by the particle metallurgy process. Its sophisticated alloy mix was specifically developed to provide the extreme wear resistance and high compressive strength needed in industrial cutting, blanking, and punching operations. Amazingly, its exceptionally fine, homogeneous microstructure also makes it readily machinable and easy to heat treat. As a blade steel, these qualities translate to outstanding edge retention and excellent toughness.
K390’s advanced alloy composition includes nearly 2.50% carbon, as well as chromium, molybdenum, manganese, vanadium, tungsten, cobalt, and silicon. K390 is a true tool steel, however, not a stainless steel, so it must be properly maintained to prevent corrosion.
All the other features of this amazingly compact cutting tool are the defining qualities of the popular Ladybug Lightweight, including a fiberglass-reinforced-nylon (FRN) handle with Bi-Directional Texturing, a sturdy back lock mechanism, and a Trademark Round Hole in the blade that is much more user friendly than the nail nick of a conventional pocketknife.
