Benchmade Morpho 51 (BCM-51) Balisong Butterfly Knife
The Benchmade Morpho 51 is a full-size balisong (butterfly) knife built for smooth, confident flipping and everyday carry. Its 4.25" modified spear-point blade is ground from D2 tool steel with a clean satin finish, riding on titanium liners inside black G10 handles for a balanced, durable feel. A dependable spring latch keeps the Benchmade Morpho 51 closed securely between flips. This model is discontinued and no longer produced, which makes a clean Benchmade Morpho 51 a sought-after collectible for balisong fans.
