The Numen S600 from Extrema Ratio is a survival fixed blade knife equipped without compromise 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 construction ensures maximum stability and balance. Thanks to its robust design, the knife is perfectly suited for heavy woodwork, batoning, cutting tough materials, and use under the harshest conditions – whether for expeditions, survival, or special tasks.

The ergonomically designed handle made of G10 material provides a secure grip, even in wet conditions or when wearing gloves. The finish and construction emphasize the commitment to readiness and performance far beyond normal outdoor tools.

Thus, the Numen S600 is not aimed at casual users, but at those who need a tool they can rely on unconditionally.
