Heretic Knives embodies innovation, quality, and a generational passion for crafting exceptional blades. Founded by Anthony Marfione Jr., the company grew from a rich legacy of knife-making established by his father, Anthony Marfione Sr., the founder of Microtech Knives. While Heretic Knives has successfully carved out its own space in the industry, its roots remain deeply connected to the Marfione family’s commitment to pushing the boundaries of what a knife can achieve.

Anthony Jr.'s journey into knife-making started early. Growing up in a family that lived and breathed blades, he and his brother Sean were immersed in the craft from childhood. The Marfione boys mimicked their father’s work, turning bicycles upside down to simulate grinding blades and crafting makeshift “knives” from wood. These formative years not only instilled a deep appreciation for hard work but also set the stage for their future endeavors.

By the time Anthony Jr. officially joined the family business at Microtech, he had already developed a strong foundation. From making boxes to assembling lanyards, he was involved in every aspect of production. This hands-on experience allowed him to learn the intricacies of knife manufacturing and the challenges of maintaining quality and innovation in an ever-competitive market.

In 2015, Anthony Jr. decided to strike out on his own, founding Heretic Knives. While it was a bold move, it wasn’t without challenges. Launching a knife company in an industry dominated by established names meant Heretic had to offer something distinctive. Drawing from his years at Microtech and his own vision, Anthony Jr. set out to create knives that combined cutting-edge technology with a personal touch.

Heretic Knives quickly gained recognition for its innovative designs and commitment to quality. The company’s focus on automatics and out-the-front (OTF) knives placed it in direct competition with some of the biggest names in the industry, including Microtech. However, this competition was fueled by mutual respect and familial camaraderie rather than rivalry.

Heretic Knives stands out for its dedication to producing unique, high-performance knives. The company prides itself on maintaining U.S.-based production, with all of its components manufactured in-house or sourced domestically. This commitment not only supports local industry but also ensures the quality and consistency that Heretic’s customers have come to expect.

One of Heretic’s defining philosophies is the belief in continuous improvement. Anthony Jr. emphasizes the importance of hands-on mentorship, both in sharpening blades to perfection and in cultivating a team capable of maintaining the brand’s high standards. The company has also begun expanding beyond automatic knives, with recent ventures into manual folders, slip joints, and other styles to broaden its appeal.

Heretic Knives is more than just a business; it’s a continuation of a family legacy. The Marfione family’s dedication to knife-making is evident in every blade produced, from the sharpness of the edge to the precision of the design. Anthony Jr. has taken the lessons learned from his father and applied them to create a brand that stands on its own, while still honoring the traditions that shaped it.

As Heretic Knives moves forward, the company remains focused on innovation and expanding its product line. Recent releases, such as the newly released Nyx OTF and the updated Pariah, showcase the brand’s commitment to blending aesthetics with functionality. Upcoming projects, including collaborations and new designs, promise to keep Heretic at the forefront of the industry.

In the words of Anthony Jr., “We’re always going to be making OTFs and automatics, that’s our DNA, but we’re also exploring new territory. The key is staying true to who we are while continuing to evolve.” With a foundation rooted in family, hard work, and a passion for knives, Heretic Knives is poised to continue making an impact for generations to come.
