Heretic Knife Hydra R/E Purple Aluminum, Black DLC/Satin MagnaCut by Tony Marfione Jr.

Hydra R/E Purple Aluminum, Black DLC/Satin, one of the most refined OTF (Out The Front) automatic knives on the market. An exceptional knife, created by Anthony Marfione Jr., owner of Heretic Knives, a symbol of excellence and precision. The construction, in 6061-T6 aluminum, emphasizes its elegance and strength, the blade, made of what is now considered the best steel for CPM MagnaCut knives, providing excellent cutting properties. The knife's opening mechanism, operates in S/A (Single Action) mode with tremendous force and power, allowing the blade to open instantly and securely. This is a feature that sets the Hydra R/E apart from other automatic knives. However, what really sets this knife apart is its superior fit and finish. Every detail, from the Handle to the blade, has been designed with comfort and functionality in mind. The knife's ergonomic Handle is designed to provide a secure grip, and its weight helps absorb energy when opening. The Hydra R/E is not just a knife, it is a work of functional art. Its unique design and exceptional quality make it a product that deserves a place in any knife collection. It is a true symbol of luxury and sophistication.

CPM MagnaCut - powder stainless steel produced by the Crucible® Particle Metallurgy (CPM) process hardened between 60.5-62.5 HRC. The high content of vanadium 4.0% (V), molybdenum 2.0% (Mo) and niobium 2.0% (Nb) guarantees accuracy and purity unmatched by more “conventional” steels. Designed and developed specifically for blade production by Larrin Thomas, it meets all the requirements of knife enthusiasts. With CPM, MagnaCut was able to create a steel that combines unique properties like no other knife steel. The result is a blade material that offers a remarkable balance of wear resistance, strength and corrosion resistance. There is no other steel on the world market today that offers a comparable combination of superior properties. This exceptional steel is produced at Crucible® Industries' U.S. steel mills.

S/A (Single Action) OTF - a knife with a blade that can be ejected by pressing a button, but once ejected, the blade must be retracted by hand. This means that the blade can be ejected in less than a second, making this type of OTF very fast. However, the blade must be retracted when finished by pulling the handle, usually located on the back of the handle. One of the main advantages of single-action OTFs is the simplified mechanism which makes them very strong and very durable. They require fewer parts, so there are fewer components that can break. This simplicity also means the knife is less prone to failure during use.

DLC (Diamond Like Carbon) durability of the blade surface is enhanced with a matte black nanocomposite coating that exhibits unique properties such as exceptional hardness and low friction, as well as excellent corrosion protection. It is one of the most resistant coatings to scratches and abrasion that are used in the industry, including the knife industry.

Blade - R/E (Recurve Edge) type with a single cutting edge. The blade with an elegant Two Tone finish, the grinds coated with black DLC coating, the rest satin-finished. Plain blade, derived with a high concave grind (Hollow Grind), providing excellent cutting properties. As a result, the knife has excellent piercing properties while maintaining its strength. On the back there are characteristic “ribs”, reminiscent of the mythical Hydra. The mechanism of extending the blade by means of a mothballed drop-shaped button, located under the thumb, requires for safety to apply a specific force to overcome the resistance of the spring.

Handle - made on CNC milling machines with excellent precision, from anodized 6061-T6 aluminum. There are notches (jimping) on the Handle for a more secure grip. The slim design allows the knife to be tucked into any pocket. A single-position (right) deep-carry clip, allows the knife to be carried discreetly in a pocket in tip-down position (blade tip down). The back of the Handle extends to retract the blade and tighten the spring for the next opening.
