A unique knife with a unique sheath.

Extrema Ratio developed the Glauca B1 Folder with strong input between Extrema Ratio and the French Military to create this unusual folder.

The tip of the blade looks like a tanto with sharpening on both sides. The Glauca B1 review by "Fog Horn" calls it a "double tanto". The double guard (with lanyard holes) are extensions of the blade. The blade is partially serrated.

A special tool for cutting plastic (i.e. plastic handcuffs) is safely incorporated in the handle and you can access this by lifting a lever on the top of the handle. This handle is specially shaped to give you exceptional gripping power. The Glauca B1 also has a window breaker on the handle end. The clip is reversible.

The Glauca B1 also has a manually activated locking mechanism which should be used to provide you with an additional level of safety.

This unusual folder is accompanied by an unusual sheath. This substantial sheath is formed so you carry the Glauca B1 as a fixed blade. It is a wide sheath structured to have several carry positions. It is MOLLE compatible. It can also be carried on a belt or on a side fixing. Has an additional strap for this. NOTE: A section on the front of the sheath is magnetized.
