Spartan Blades Formido Fixed Knife 3.87in Plain Black Straight Back SB39BKKYBK

The Spartan Blades Formido Black is a purpose-driven fixed blade built for those who value strength, speed, and precision in a streamlined design. Created by Curtis Iovito, Spartan Blades’ founder and lead designer, the Formido reflects the brand’s uncompromising approach to performance and craftsmanship. Every detail is intentional, resulting in a compact knife that carries easily while delivering the confidence and capability expected from a Spartan Blades design.

With an overall length of approximately 8.75 inches, the Formido offers a commanding presence without becoming unwieldy. Its straight-back blade profile is designed for reliable utility and self-defense geometry, providing excellent point control and clean cutting lines. The blade measures about 3.87 inches in length with a thickness of roughly 0.18 inches, striking a smart balance between cutting efficiency and structural strength. This geometry gives the Formido a solid, authoritative feel while remaining agile and responsive in hand.

The blade is crafted from CPM MagnaCut stainless steel, one of the most advanced blade steels available today. Heat treated to approximately 61–63 HRC, MagnaCut delivers an exceptional blend of edge retention, toughness, and corrosion resistance. This allows the Formido to maintain a sharp working edge through demanding use while remaining resilient in a wide range of environments. The black SpartaCoat PVD finish enhances durability, reduces glare, and adds a clean, tactical look that complements the knife’s mission-focused design.

A skeletonized handle and tang keep weight to a minimum without compromising strength. At just 2.8 ounces, the Formido is remarkably light for a fixed blade of this size, making it comfortable to carry for extended periods. The minimalist handle design promotes fast indexing and secure control, allowing the knife to feel natural and balanced during use. Its construction reflects Spartan Blades’ philosophy of eliminating unnecessary material while preserving structural integrity.

Carry versatility is a core strength of the Formido. It comes with a black Kydex retention sheath that’s molded for a secure hold and quick access. The sheath is designed to support multiple carry positions, including inside-the-waistband, belt carry, or neck carry, depending on user preference. Included hardware allows you to configure the setup that best fits your daily routine, making the Formido adaptable to a wide range of carry styles.

Proudly made in the United States, the Spartan Blades Formido Black represents disciplined engineering, premium materials, and thoughtful execution. It’s compact without feeling limited, lightweight without sacrificing strength, and refined without losing its edge.
