This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
Manticore S D/E Black Frag Aluminum, P/S Black/Satin ultralight and compact automatic knife. Equipped with a hellishly fast mechanism that extends the razor-sharp blade. 100% made and assembled in the USA. Designed by Anthony Marfione Jr. knifemaker and owner of Heretic Knives.
Operating in D/A (Double Action) mode, it features an innovative locking mechanism for unparalleled performance and reliability. Designed with precision engineering and built with the highest quality materials. Offers the same features as the larger OTF (Out The Front) of the Manticore line. Silky-smooth operation of a powerful one-handed unfolding and folding mechanism that begins with a gradual thumb-slide of the stepped slide, so you can fire the blade with confidence.
CPM MagnaCut powdered stainless steel manufactured using the Crucible® Particle Metallurgy (CPM) process hardened to 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 succeeded in creating a steel that combines the unique properties of knife steels like no other. 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 manufactured at Crucible® Industries' American steel mills.
Blade - machine ground D/E (Double Edge Dagger) type with a double-edged symmetrical blade, serrated on one side. The blade with an elegant Two Tone finish, the grinds coated with a black coating, the rest of the blade satin-finished, brought out with a high flat grind (Flat Grind), providing excellent cutting properties. As a result, while maintaining high strength, the knife has excellent piercing properties. The strong mechanism of extending / retracting the blade with the help of a moled Thumb Slide, a stepped slide, requires for safety the application of a specific force to overcome the resistance of the spring. The method of opening provides seamless opening for both right and left-handed people.
Handle - made with excellent precision in 3D technology on CNC milling machines, from anodized 6061-T6 aluminum. The distinctive texture of the Handle imitating the surface of a fragmentation grenade (Frag Pattern), in addition to visual value, makes the knife does not slip in the hand during use. There are notches (jimping) on the back and bottom of the handle for a more secure grip. The slim profile and milled two-position (right/left) solid deep-carry clip allow the knife to be carried discreetly in any pocket in tip-down position (blade tip down). The Handle is finished with a lanyard hole, a rope hole and a glass breaker.
