The Heretic Custom Hydra Single Action OTF Automatic represents the highest tier of modern automatic knife craftsmanship, blending bold mechanical innovation with rare materials and precision American manufacturing. Designed by master knifemaker Anthony Marfione, the Hydra has earned a reputation as one of the most distinctive and mechanically impressive out-the-front automatics available today. In this custom configuration, every element reflects a commitment to performance, exclusivity, and refined design.
The 3.625” tanto blade is forged from Vegas Forge Reptilian Damascus steel and finished with a DLC (diamond-like carbon) coating. The Damascus pattern beneath the deep black coating creates a striking reptilian texture that gives the blade extraordinary visual depth while maintaining the durability expected from a hard-use automatic. The tanto blade shape offers exceptional tip strength and piercing capability, paired with a straight primary edge that excels at controlled cutting tasks. The DLC finish adds remarkable surface hardness and wear resistance while enhancing the blade’s stealthy appearance.
The Hydra operates as a powerful single-action out-the-front automatic driven by its distinctive aluminum charging handle. The charging system allows the user to arm the mechanism before firing the blade forward with authority, delivering a fast, decisive deployment that showcases the knife’s sophisticated internal engineering. Once deployed, the blade locks securely in place, creating a rock-solid platform ready for serious use.
A defining feature of the Hydra is its innovative button safety mechanism. The textured firing button is protected by a sculpted aluminum swivel cover that rotates into position, preventing accidental activation while adding a dramatic mechanical element to the knife’s design. This pioneering safety system reflects the level of thoughtful engineering behind the Hydra platform.
The chassis is constructed from black carbon fiber, offering exceptional strength with a refined, lightweight feel. DLC-coated hardware complements the blade and enhances long-term durability, while the DLC-coated pocket clip features a glider ball that allows the knife to move smoothly in and out of the pocket without excessive wear.
Measuring 5.3” closed and weighing 5.2 ounces, the Hydra delivers a substantial presence with the balance and precision expected from a premium automatic knife. Each custom piece includes a metal certificate of authenticity and a high-quality zippered nylon storage case. Proudly made in the USA, this knife represents the uncompromising standards of Heretic Knives and Anthony Marfione’s unmistakable design vision.
