The Heretic Manticore X is the full size flagship of the Manticore series and the model Heretic calls its best seller. Its 3.70 inch blade gives the most reach in the family, and it is the knife the smaller Manticores were scaled from, built by Heretic Knives in Sebastian, Florida. Our guide to the Heretic Manticore series compares all three sizes.
The Manticore X measures 9.25 inches open and 5.50 inches closed at about 4.5 ounces, on 0.125 inch stock and a 0.47 inch thick handle. The Manticore E is scaled to 86 percent of the X at 7.9 inches and 3.3 ounces, and the Manticore S shrinks to 6.5 inches and 1.7 ounces. Choose the X when blade length and a full four finger grip matter more than pocket space.
A stepped thumb slide fires and retracts the blade with one hand, and the long handle gives leverage and control for real cutting work. A hardened steel glass breaker caps the handle for emergency use, a useful feature for first responders and anyone who wants a full size option among our OTF knives. The clip mounts tip down for right or left hand carry.
Every production Manticore X runs CPM MagnaCut. Choose a bowie, tanto, recurve, or double edge dagger, in plain, partially serrated, or fully serrated edges, plus a Vegas Forge blued Damascus tanto with mother of pearl inlays. Our comparison of every major knife steel covers MagnaCut.
The aluminum handle comes with Grenade Grip or Frag textures for a sure hold in wet or gloved hands, in black, OD green, red, blue, and Breakthrough purple. Inlay builds add Ultem and FatCarbon in Reptile, Scorpion, and Subzero themes, alongside the Bounty Hunter series and the A10 Edition. Every Manticore X is made in the USA.
