WE SUPPORT OURVETERANS & COPSMeet the Fat Boy Blackout, the knife that started it all for Off-Grid back in 2016. This was our very first release: a compact, overbuilt workhorse that earned its "pocket tank" nickname from day one. If you are looking for a chunky, no-nonsense utility blade that punches way above its size, this is it.
Designed with real-world use in mind, the Fat Boy quickly gained a loyal following for its rock-solid feel, compact footprint, and go-anywhere versatility. From job sites and glove boxes to hiking trails and camp kitchens, it has proven itself in just about every environment imaginable. Its wide, stout blade makes quick work of cutting tasks, while the button lock adds an extra layer of safety and ease for one-handed operation.
Nearly a decade later, the Fat Boy remains a fan favorite, trusted by thousands of users who demand performance, durability, and simplicity in their everyday carry. Whether you are a longtime Off-Grid supporter or just discovering the brand, the Fat Boy Blackout is where the legacy begins.
Known for its excellent corrosion resistance, easy sharpening, and ability to take a razor-sharp edge, AUS-8 is a reliable workhorse steel. The black Titanium Nitride coating boosts durability and edge retention, and adds a stealthy, non-reflective finish.
The Fat Boy’s signature button lock lets you close the blade easily and safely with one hand. Press the center button to disengage the internal liner lock. Simple, smooth, and secure every time.
The Fat Boy is a true pocket tank. Is it heavy for its size? Absolutely. And we would not have it any other way, and neither would our customers. Built to be tough and versatile, the Fat Boy handles it all: home projects, job site tasks, outdoor adventures, glove box backup, and even campsite food prep. It is the do-it-all EDC that is always ready for action.
Despite its compact size, the Fat Boy is built for big hands. The ergonomic handle offers a secure, comfortable grip with a jimped thumb ramp for precise control and a lanyard hole for added carry options. Strong, safe, and ready to work.
The Fat Boy’s wide-radius, triangular blade geometry delivers cutting performance that rivals knives three times its size. Powerful, efficient, and built for serious slicing. Backed by our lifetime warranty, like every Off-Grid blade.
RUGGED DESIGN. RAZOR PERFORMANCE.
