Extrema Ratio 04.1000.0133/Blk Mf1 Black
Unleash elite-level performance with the Extrema Ratio MF1 Black Knife—a precision-engineered tool that blends uncompromising strength with battlefield-inspired versatility. From the sleek matte finish of the MF1 Black to the rugged Desert Warfare edition, every variant is crafted to excel in the most demanding environments. Whether you’re storming through thick brush, performing surgical fieldwork, or tackling everyday emergencies, the MF1 stands ready with razor-sharp confidence.
At the heart of the MF1 lies a 92 mm BöHLER N690 steel blade tempered to 58 HRC. This premium alloy edge holds its sharpness through relentless use, slicing cleanly through rope, wood, and synthetic materials while resisting corrosion in wet, salty conditions. The flat grind delivers a perfect balance of slicing agility and chopping power, making light work of camp chores and tactical applications alike.
The MF1’s handle is a study in ergonomic efficiency. Machined from anticorodal anodized aluminum, it offers a rock-solid grip that stays firm even in slippery hands. The low-profile guard and pronounced finger choil ensure precise control on every cut, while the perfectly weighted 166 g design feels like an extension of your arm. Slip it into the included sheath and carry it comfortably on belt or pack, knowing it’s always within reach.
For those who demand extra utility, the MF1 BC (“Belt Cutter”) variants integrate a concealed industrial-grade cutter blade directly into the handle—ideal for quick-release scenarios, from seatbelts to webbing. A flip-out screwdriver tip lives inside the hilt, ready to fine-tune your firearm optics or tackle on-the-go repairs. Both tools swap out or stow away in seconds, so you stay mission-focused rather than tool-tweaking.
Choose your battlefield profile: MF1 Black for a stealthy presence, Black Rough for enhanced grip texture, or Desert Warfare for sand-ready camouflage. The BC lineup mirrors these finishes with the added rescue-ready cutter. Every model ships with a Mil-Spec burnished blade that absorbs glare, plus a waterproof sheath engineered for silent, secure draw.
Elevate your preparedness with a knife designed to outlast the elements and outperform the competition. When seconds count and failure is not an option, trust the Extrema Ratio MF1 to deliver precision, durability, and multi-tool adaptability—wherever your mission leads.
