The Spyderco Mantra Series offers an advanced folding flipper design, that's available in a variety of formats. The Mantra 1 has an M4 steel drop point blade and a titanium frame lock handle. The Mantra 2 has the same titanium handle as the 1, but employs a streamlined M4 steel blade that narrows towards the tip for versatile cutting performance. The Mantra 3 changes things up a bit with a lightweight carbon fiber handle and a sturdy compression lock. Whether you choose the 1, 2, or 3, you can't go wrong with the Spyderco Mantra!
