Extrema Ratio Knives KreiosExtrema Ratio Knives Numen S600 Black
The Numen S600 from Extrema Ratio is an uncompromisingly equipped survival fixed blade knife for the highest demands. The blade made of Böhler S600 steel – a tool steel with extremely high hardness (approx. 64 HRC) – guarantees outstanding edge retention, wear resistance, and durability.
The full tang design ensures maximum stability and balance. Thanks to its robust features, the knife is well suited for heavy woodwork, batoning, cutting tough materials, and use under the harshest conditions – whether expedition, survival, or special tasks.
The ergonomically shaped handle made of G10 material offers a secure grip, even when wet or wearing gloves. The finish and construction underline the claim to readiness and performance far beyond ordinary outdoor tools.
Thus, the Numen S600 is not aimed at occasional users but at those who need a tool they can rely on unconditionally.
The Numen S600 is a true premium tool: With first-class steel, robust construction, and clear focus on extreme use, it appeals to professionals, outdoor enthusiasts, and survival experts. Those who cut, chop, or baton in the forest, on expeditions, or under difficult conditions get a knife that works when others give up. For everyday use, it is rather oversized – but precisely where strain matters, it shows its strength.
