Five years ago Reiff Knives hit the outdoor knife scene with their F4 model – a full sized American Made premium fixed blade that was designed for rigorous outdoor use in both survival and bushcraft tasks. The original F4 was and its larger cousin the F6 were a success that helped establish Reiff Knives as respected name among discerning outdoor enthusiasts and professionals.
Since the initial launch of the F4 and F6 Reiff has released numerous outdoor style knives, and few EDC sized knives, and most recently their first foray into tactical knives with the thoughtfully designed and incredibly well built Vicon.
Always Improving
While the original F4 has seen some variants over the years including a scandi grind and Magnacut steel variants, the knife remained largely unchanged from its original form factor. As someone who was fortunate enough to receive one of the pre-release production prototypes and has relied on it ever since then I can honestly say the original F4 is an exceptional knife.
Why did Reiff make changes to the F4?
If you spend any time talking to Stu Shank one of the founders of Reiff Knives you will quickly learn that “good enough” is not a phrase that exists in his vocabulary. Stu is one of the most discerning and detail-oriented knife enthusiasts I have ever encountered – and that mentality definitely came with him when he launched Reiff Knives.
Every model Reiff releases has gone through extensive prototyping until everything about the model is up to Reiff’s high standards and even after Stu spends a great deal of time speaking with industry professionals who use their knives to help make changes in future iterations that could make an already amazing tool even better!
What’s New in the Reiff F4 Gen2
The most obvious change in the F4 Gen2 is the higher saber grind, but what you won’t see with the naked eye is also tweaks in the edge geometry. The thinner edge and higher saber grind can significantly improve slicing tasks. The choice to use CPM-3V helps ensure the thinner edge and reduces the chance of chipping and as a bonus CPM-3V is far easier to sharpen in the field compared to Magnacut.
Reiff also made some minor changes to the blade profile and handle profile that improve overall comfort and usability. The handle scales are changeable and feature and new texture pattern that significant enhances positive grip during hard use tasks.
The sheath has been updated to a custom modular ambidextrous sheath very similar to the to what is found on Reiff’s Vicon Tactical Knife. The custom clip is excellent for belt carry, but any number of mounting options can be used with the sheath.
Customization Options
The Reiff Knives F4 Gen2 is launching in three available finishes – classic stone wash, black DLC, and flat dark earth PVD. For handle materials you have the option of black or OD green G10 and black or green canvas micarta.
