Extrema Ratio Knife A.M.F. Black
The Extrema Ratio A.M.F. Black is a relentlessly designed survival and duty knife with a fixed blade. With a blade length of 206 mm and an overall length of 345 mm, it combines impressive size with thoughtful modularity: every part can be easily disassembled for cleaning or maintenance.
The blade made of Böhler N690 steel (approx. 58 HRC) offers outstanding edge retention and resistance to rust, complemented by a MIL-C-13924 coating that minimizes reflections and provides a distant-tactical appearance. The handle is made of Forprene and is designed for high stress; together with the pronounced hand guard, it also allows rough handling in the field.
The knife comes with a sturdy Cordura sheath, compatible with MOLLE systems and equipped with carrying options for survival kits. Whether for extreme outdoor use, survival gear, or professional use – the A.M.F. Black makes no compromises.
Knife sales in Switzerland – Important notes
At Alpine Fox you will find only knives that are not classified as weapons under the Swiss Weapons Act (WG). We deliberately carry only models whose possession and purchase in Switzerland is fully legal.
There is only one requirement for purchasing a knife:
You must be at least 18 years old.
We still recommend familiarizing yourself with the legal basics when acquiring knives and handling these products responsibly.
