Produced by BÓ§hler-Uddeholm, its advanced alloy composition offers exceptional edge retention and toughness and makes it an ideal choice for steel connoisseurs.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.
