Product Description

The Heretic Knives Hydra V4 OTF H408-10A-T pairs a 2-tone CPM MagnaCut recurve blade with a black aluminum handle, bringing Heretic's push-button OTF mechanism to the Hydra platform in a slicing-focused blade shape.

CPM MagnaCut is Crucible's stainless steel engineered specifically for knife blades by metallurgist Larrin Thomas, rather than optimizing for one property, MagnaCut is formulated to deliver strong edge retention, corrosion resistance, and toughness simultaneously, closing the gap that usually forces a tradeoff between the three. Its balanced carbide structure keeps it easier to sharpen than extreme high-vanadium steels like CPM-S90V, while still outperforming older workhorse stainless steels like D2, 154CM, and CPM-S30V on corrosion resistance and edge stability.

The recurve grind on this Hydra V4 adds extra belly and cutting length along the edge compared to a straight blade of the same overall length, which helps on slicing tasks like rope, cardboard, or cordage where a straight edge loses efficiency partway through the cut.

The 2-tone finish combines two distinct surface treatments on the same CPM MagnaCut blade for visual contrast, the steel and performance stay the same regardless of which finish combination is applied.

The out-the-front mechanism fires the blade straight out of the front of the handle at the push of a button and retracts it the same way, no manual flip, thumb stud, or disengage step required.

• Blade: 3.62" CPM MagnaCut recurve blade, 2-tone finish, balanced edge retention, corrosion resistance, and toughness; recurve grind adds extra belly for slicing tasks over a straight edge.
