SPYDERCO Manbug Lightweight Blue Folding Knife (MFPK390)

If you want a knife that is sized to fit on a keychain without compromising in quality, Spyderco has got you covered with the Manbug Lightweight Folding Knife. It may be tiny, but it's a fully capable knife built on Spyderco's reliable lockback mechanism. The handles have that signature bi-directional texturing that adds grip without discomfort, and the full-flat grind blade opens easily with the built-in thumbhole.

This special variant can be easily spotted wearing attractive Blue FRN scales which indicate the blade is Bohler K390 Microclean. K390 is a high-alloy particle metallurgy tool steel with high amounts of vanadium, tungsten, and cobalt to give the blade tons of edge retention and toughness.
