High quality, extremely collectible handmade knives since the 1800s.
SHOP CASE KNIVESThe Heretic Hydra V4 OTF Auto Recurve Cel Shade Frankenstein is a high-performance automatic knife that blends advanced engineering with bold, collector-ready aesthetics. Since its introduction in 2015, the Hydra line has set the standard for out-the-front knives, pioneering a button safety that ensures secure handling without sacrificing speed or reliability. The textured firing button is guarded by a sculpted titanium swivel cover, giving both visual impact and functional assurance, so you can deploy the blade with confidence every time.
Built in the USA, the Hydra V4 features a single-action OTF mechanism that allows for rapid blade deployment with a smooth push-button opener. Once deployed, the blade locks securely into place, providing stability and control for cutting tasks that demand precision. Retraction is just as reliable, and the knife’s ergonomically designed aluminum handle ensures a solid grip whether you’re handling it in the field or on display. The tip-down, right-hand carry clip adds convenience, keeping the knife ready without interfering with everyday movement.
The 3.625-inch recurve blade is forged from premium CPM Magnacut steel, combining exceptional edge retention with toughness and corrosion resistance. Its plain edge and hollow grind offer optimal slicing performance, while the unique Cel Shade Frankenstein Monster finish makes a striking impression. This UV-reactive finish glows under blacklight, creating a visual effect that elevates the knife from a practical tool to a standout piece for collectors. The handle mirrors the blade’s aesthetic with matching colors and sharp detailing, uniting form and function in a cohesive design.
With a closed length of 5.30 inches, an overall length of 9.125 inches, and a weight of 5.20 ounces, the Hydra V4 balances size, portability, and ergonomics. Every component reflects Heretic Knives’ commitment to precision and quality—from the meticulously milled handle and blade to the finely tuned push-button mechanism. This knife is ideal for those who demand reliable performance, eye-catching design, and the confidence that comes with owning a finely crafted American-made OTF automatic. Unleash the monster in your pocket with the Heretic Hydra V4 Cel Shade Frankenstein—power, precision, and electrifying style. Available at SMKW.
