The Heretic Knives Hydra is a powerful, single action, out-the-front automatic built in an everyday carry size. Simple and robust, the Single Action Hydra is a thing of beauty and a reliable cutting tool that is a joy to use and operate. This version comes with a two-tone black Elmax drop point blade, black aluminum frame and raw Copper top.

Brand new, direct from Heretic Knives, USA.

Blade: The sleek, hollow saber ground, drop point blade combines powerful performance and durability with a striking look further enhanced by aggressive scalloping on the spine. Satin flats and black coated grinds offer stylish visual appeal. Deployment via the strong, single action automatic mechanism is fast and decisive. Slide the stainless steel safety over and press the button. Action is strong, so keep a solid grip.

Handle: A milled, hard anodized aluminum frame and hefty raw copper top provides a full sized handle with enough real estate for a solid grip even in gloves. Shaped perfectly for a secure yet comfortable grip, the handle has strategically placed jimping for enhanced traction. Company, model and serial number markings on charging slide for a clean look. Access the button lock the same way you did for deployment to disengage the lock. Pull the slide down using the attached lanyard to charge the spring, making it ready for deployment.

Carries via a right-hand milled titanium pocket clip with tension ball.

Bohler Elmax: Bohler Elmax is a popular choice for high-end user grade knives thanks to its excellent edge retention and corrosion resistance. Elmax has similar performance to the American CPM-S30V/S35VN, falling between the two in terms of edge retention and toughness, with S35VN level corrosion resistance and similar sharpening response.
