Limit 1 per order. Web Only.

The Heretic Knives Hydra V4 single-action OTF is a limited-edition statement built with zero tolerance for compromise. Designed as an out-the-front automatic, it delivers controlled aggression, premium materials, and mechanical confidence for users and collectors who demand precision with attitude. Every detail feels intentional, from the authoritative action to the refined finishes that separate it from ordinary production knives.

At the heart of the Hydra V4 is a DLC-coated tanto blade made from 20CV Super Steel. This high-performance steel is trusted for its exceptional edge retention, wear resistance, and corrosion resistance, holding a razor edge far longer than standard blade materials. The tanto profile reinforces the tip for hard use while maintaining clean, tactical lines that look every bit as serious as they perform. The dark DLC coating adds durability while keeping glare down and aesthetics sharp.

The single-action out-the-front automatic mechanism delivers decisive deployment with a solid, confidence-inspiring lockup. Each firing cycle feels deliberate and powerful, built around strength and reliability rather than shortcuts. It’s a system meant for those who appreciate mechanical integrity and expect consistent performance under pressure.

The handle is built on a lightweight carbon fiber chassis that keeps carry weight low while maintaining rigidity and balance. Hand-flamed titanium accents on the button cover and charging plate add vivid, one-of-a-kind coloration, while the machined rollerball pocket clip ensures smooth, secure carry. Together, these elements create a knife that feels fast, responsive, and unmistakably high-end in hand.
