Tiny But Mighty. A Keychain-Sized Cutter With Premium Steel and Featherweight Form.

The ManBug 3 CPM-SPY27 is Spyderco’s ultra-compact folder that packs serious performance into a sub-1 oz frame. Featuring their proprietary CPM-SPY27 steel and a full-flat-ground blade, this Japan-made knife is ideal for keychain carry, backup use, or minimalist EDC.

The cobalt blue FRN handle identifies it as part of the SPY27 family, offering lightweight strength and a secure lockback mechanism. Weighing less than a single AA battery, it is perfect for keychains, neck lanyards, or pocket drop. SPY27 offers elite edge retention, corrosion resistance, and ease of sharpening, and the cobalt blue handle marks its SPY27 pedigree.
