The Extrema Ratio Glauca G1, an evolution of the original Glauca model, incorporates specialised features designed specifically for Germany's elite GSG9 Bundespolizei unit.

 

Its handle is crafted from anodised Anticorodal aluminum in a tactical mud color, providing durability and grip. 

 

The knife is equipped with a tungsten carbide glass breaker on the pommel and a two-position clip (one of which allows a front attachment). On the back, it includes a lockable stainless-steel marlin spike and a foldable rescue tool for rapid emergency cuts.

 

The blade is secured with a proven Liner-Lock system, reinforced by a manually activated secondary safety. It features a drop-point blade made from Böhler N690 steel, hardened to 58 HRC, with Extrema Ratio's signature MIL-C-13924 black finish.
