The Heretic Knives Manticore X Custom OTF is a mint-condition pre-owned double-action out-the-front automatic knife from a recent collection purchase by We Buy Knife Collections. This custom build is serial number 011 and features a hand-ground Elmax tanto blade with two-tone DLC stonewash grinds, satin hand-rubbed flats, and Fat Carbon Black Camo inlay work.
As the largest model in the Manticore series, the Manticore X gives collectors a substantial 9.20-inch overall profile while still carrying cleanly at just 4.30 ounces. The 5.50-inch black anodized aluminum handle has contoured 3D machining, strategically placed scallops, satin flats, and matching Fat Carbon Black Camo inlays. Additionally, the Fat Carbon Black Camo slide/button ties the handle and blade details together with a cohesive custom finish.
Heretic Knives Manticore X Custom with Elmax Tanto Blade
This Heretic Knives Manticore X Custom stands apart from standard configurations through its hand-ground tanto blade, custom inlay package, and serial-numbered presentation. The Elmax blade combines a strong tanto tip with a long, sleek profile, while the two-tone DLC stonewash and satin finish create excellent contrast across the grinds and flats. Moreover, the blade inlay gives the knife a distinctive custom look without overwhelming the clean tactical architecture of the design.
The automatic action deploys and retracts through the thumb slide, giving the knife the fast, confident feel collectors expect from a premium OTF. The double-action mechanism feels appropriate for a high-end Heretic build, and the larger Manticore X format gives the handle enough length for a secure grip.
Fat Carbon Black Camo, DLC Hardware, and Custom OTF Details
The handle uses black anodized aircraft-grade aluminum with Black Camo Fat Carbon inlays and satin-framed flats. Because the body stays visually sterile, the inlays become the focal point. Meanwhile, the DLC-coated hardware, hardened steel glass breaker, and 3D stainless steel tension-ball pocket clip keep the build both functional and collector-worthy.
The clip is set up for right-hand, tip-down carry and is marked with the serial number. This piece also includes the original box, microfiber bag, zippered nylon storage pouch, rocker patch, and signed Heretic certificate of authenticity / Certificate of Badassery.
