The Heretic Hydra V4 OTF: A Bold New Miami Vice Edition

Few knives capture the imagination of collectors like the Heretic Hydra series. For years, the Hydra has been a benchmark in OTF (Out-the-Front) automatic design, combining innovative engineering with a bold aesthetic. Now, in 2025, Heretic Knives has raised the bar again with the Hydra V4 OTF Automatic Knife – Cell-Shaded Miami Vice edition.

Launching September 2nd at 12PM EST, this release is already generating buzz among knife enthusiasts, EDC carriers, and collectors alike.

The Hydra Legacy

The Hydra has always stood apart in the OTF world. Unlike many double-action OTF knives, the Hydra’s single-action system uses a charging handle retraction to reset the blade after deployment. It’s a design that offers power, reliability, and a distinctive feel, instantly setting it apart from the crowd.

The V4 redesign refines this system with smoother mechanics, updated ergonomics, and an even more robust build — making it a worthy successor in the Hydra lineage.

Miami Vice Reimagined

What makes this release so captivating is the Cell-Shaded Miami Vice finish. Heretic has taken inspiration from the neon glow of the 1980s — a retro palette of electric blues, neon pinks, and deep blacks that feels like it was pulled straight from an arcade cabinet or classic sports car lineup. 

This finish is more than just color; it’s artistry. The cell-shaded effect creates sharp transitions and bold outlines, giving the knife an almost animated, surreal presence. It looks less like a traditional tool and more like something that leapt off the screen of a graphic novel.

MagnaCut: The Modern Super Steel

Beneath the flashy exterior lies serious performance. The Hydra V4 comes equipped with a 3.6" MagnaCut tanto blade. MagnaCut has quickly become the gold standard in premium knife steels, praised for its balance of toughness, edge retention, and corrosion resistance.

Whether you’re carrying the Hydra as a working tool or showcasing it as the centerpiece of a collection, the steel ensures it’s more than just looks.
