Featherweight engineering meets full-size performance — the Biophase is built to impress.

The CIVIVI Biophase is a standout in lightweight knife design, pairing a skeletonized gray aluminum frame with coarse black G10 scales for maximum strength-to-weight efficiency. At just 2.66 oz, it’s remarkably light for its 3.48″ clip point blade, which is crafted from Nitro-V stainless steel and finished in satin for clean, low-glare utility. The blade features a flipper tab, thumb ramp, and opening slot for versatile deployment, while caged ceramic bearings ensure smooth action. A button lock mechanism provides safe, one-handed closure, and the reversible deep-carry clip makes it ambidextrous and pocket-friendly.
