Reiff Knives F6

Although it sounds like a fighter jet, the Reiff F6 CPM 3V high-alloy steel is sleek and functional. I treated this medium-to-large knife as a versatile tool for light to medium-heavy tasks, particularly in crafting.

The Reiff Knives F-Series is a tough, hard-use outdoor knife made from premium CPM 3V high alloy steel. Its drop point blades and high saber grinds result in a fine 20-degree micro convex. If you ever had a knife that you loved but wished the handle was a little longer or hand-filling, the Leuku Survival Knife might be what you’re looking for.

Creating a maul with the F6 was the first project for which the author used the Leuko-style knife.

Calling all large and extra-large hands out there! You will not be disappointed with the size of this knife handle. The full-sized G10 handle design accommodates extended use. A sure grip prevents the knife from slipping in your hand, making it safer and reducing fatigue. The thick full-tang features a skeletonized design to reduce the overall weight, making it an ideal carry companion wherever you roam.

New Breed of Leuku Survival Knife

The new Reiff Knives F6 Leuku Survival Knife features CPM MagnaCut super steel and striking green and black layered canvas micarta handle scales. Check out the F6 MagnaCut collection for all eight handle options.

The F6 is a versatile camping and survival knife. It’s sturdy enough for light chopping while remaining agile for everyday tasks. Crafted in the USA, it excels in outdoor adventures, whether processing firewood or cooking meals. The ultra-stainless CPM MagnaCut steel ensures low maintenance in wet environments.

The author batoned the Reiff F6 in the dead of winter through frozen wood for a sustainable fire.

The ergonomic handle and balanced design make the F6 feel lighter and more comfortable than others, allowing for fine work over extended periods. This makes it an ideal Leuku Survival Knife for those who need both utility and comfort.

Built from premium, American-made materials, this F6 is ready for anything. Reiff stands behind its products with exceptional customer service and an industry-leading Carry No Cares Warranty, ensuring your investment is safe.

Leuku Survival Knife Winter Test!

After a beech tree fell near my woods camp, I made a maul/mallet for batoning. Using a 24-inch bucksaw, I cut a 5-inch diameter, 8-inch long section of the tree and shaped the handle by driving the F6 CPM 3V steel into the top for a comfortable grip. Testing the Leuku Survival Knife in such a setting was essential to understand its capability.

The new Reiff Knives F6 Leuku Survival Knife is made from CPM MagnaCut super steel and has an improved 90-degree spine for striking a Ferro rod.

To test the knife, I cut a witch-hazel branch for a Figure Four trap. The F6 sliced through smoothly as I made stop-cuts and batoned the wood. I also cut a beaver-chewed stick for a stake, carving a notch for cordage and shaping it with controlled chops.

After crafting the maul and stake, I made feather sticks from dry poplar to catch sparks and then used the F6 in the kitchen. The ultra-stainless CPM MagnaCut F6 impressed me, especially the refined 90-degree spine, which surpassed the former version.

Tough and woods-worthy, the Reiff MagnaCut F6 is here to stay.
