Heretic Hydra V4 OTF Automatic Knife Battleworn Magnacut/Black H407-5A

The Heretic Knives Hydra V4 is a no-nonsense out-the-front automatic that blends top-tier engineering with hard-use muscle. Built for those who demand speed, strength, and precision, the Hydra V4 features a single-action deployment system powered by a front-facing oversized firing button with a rotating safety switch. When the blade punches out, it does so with authority—and when it's time to retract, a hidden release system tucked under the firing button ensures only the user is in control.

This model boasts a 3.625" battleworn-finished CPM MagnaCut blade, hardened to perform under pressure. The stonewashed, distressed finish isn’t just for looks—it hides wear and keeps the edge looking sharp through real-world use. MagnaCut brings exceptional corrosion resistance and edge retention to the table, making it ideal for everything from EDC to field carry.

The handle is machined from aircraft-grade aluminum and hard anodized black, offering a rock-solid grip and sleek silhouette. Jimping along the spine and sides adds extra traction in wet or gloved hands. A black DLC-coated titanium pocket clip rides tip-down, and the exposed pommel is fitted with a hardened steel glass breaker, rounding out this knife’s tactical versatility. Proudly made in the USA, the Hydra V4 stands as a formidable choice for anyone who refuses to compromise.
