Tiny knife, exotic steel. K390 performance in your pocket’s smallest corner.

Spyderco has always pushed the envelope by offering exotic blade steels in their knives. K390 MICROCLEAN, made by Bohler-Uddeholm, is a state-of-the-art cold work tool steel built for extreme wear resistance and high compressive strength — yet its fine, homogeneous microstructure keeps it easy to heat treat.

That outstanding blade material now stars in one of Spyderco’s most popular small folders. The Manbug Lightweight K390 pairs a 1.97" clip point blade with a blue FRN handle and a secure lockback — a true steel connoisseur’s keychain companion, made in Japan. The blue FRN handle and secure lockback keep this tiny folder practical, and at 0.7 ounces it’s barely there until you need it.
