ManBug - Blue FRN / K390
A uniquely practical folder, the Manbug is an amazingly handy cutting tool that is more at home in larger hands while still fitting inconspicuously in a pocket or even on a keychain.br>
Spyderco has always taken great pride in our efforts to push the envelope of performance by offering exotic blade steels in their knives. With that spirit in mind, they are proud to offer the Manbug Lightweight with a blade crafted from K390.
Manufactured by Böhler-Uddeholm, K390 MICROCLEAN is a state-of-the-art cold work tool steel produced by the particle metallurgy process. Its advanced alloy mix is enriched with high volumes of vanadium, tungsten, and cobalt offering exceptional edge retention and toughness; however, since it is not a stainless steel, care should be taken to maintain it properly to protect it from corrosion.
Collectively, these qualities make K390 an outstanding blade material for true steel connoisseurs.
