Reiff Knives is a family owned American knife company run by brothers Stu and Ben Shank, named for their great-grandmother Anna Reiff and marked by a wolf, the animal Stu calls the truest symbol of the North American outdoors: able to go it alone, at its best in a tight-knit family. The brothers grew up on their grandparents' backcountry cabin land in the Allegheny Mountains of West Virginia, learning to hunt, fish, and process game twenty minutes off any paved road, and they built Reiff as an answer to an industry full of compromise: American materials, American factories, heirloom-quality fixed blades, and no spin. The company motto is a dare: bet your life on a Reiff knife.
The F-Series is the backbone, built on CPM 3V tool steel, a chemistry chosen for near-indestructible toughness that shrugs off batoning and prying that would snap lesser blades, under full tangs and precision G-10 or micarta scales. The F3 EDC packs the formula into a 2.9 inch everyday fixed blade, the F4 Bushcraft is the do-everything 4 inch that made the brand's name, the F5 Survival and F5 Field Survival scale up for hard wilderness use, and the F6 Leuku brings Nordic hack-and-slash reach to camp chores. Where 3V sits among the toughest steels made is covered in our knife steel guide.
The catalog has grown well beyond the originals. The Vicon is Reiff's first folding knife, carrying the brand's overbuilt instincts into the pocket, while the Circadian series offers EDC-sized fixed blades in specialized blade shapes on a shared handle chassis, tuned to the rhythms of your day. The Rangewolf covers hunting duty and the S5 Glider brings a scandi grind to the bushcraft side, with CPM MagnaCut appearing across newer models at 61-63 HRC for stainless performance without surrendering toughness. Every Reiff carries a lifetime guarantee that transfers with the knife and never expires, which is exactly what heirloom quality should mean: the warranty outlives you too.
