The Extrema Ratio ULTRAMARINE Con Asola Scuba Knife is an amphibious knife developed for underwater operation to ground operation equipment and is versatile for use in challenging conditions. The special scuba nylon sheath can be worn on the ankle, or its hard ABS section can be attached by two BELT-CLIPS to either the breathing apparatus or BCD belts. This incredible knife is designed to be attached to the tactical vest, fit snugly against the body and carried inside a waterproof bag during underwater operations. 

All the user has to do, if getting rid of his diving suit after landing, is to draw the knife from its ankle sheath and place it in the tactical vest sheath. The handle material of the knife is designed with special grip and anti-slip material so that it is suitable for use with neoprene gloves.

In addition the handle is designed so that the user can distinguish between blade and handle in poor visibility conditions.

The steel tang can be used as a glass breaker/hammer. This is the solid blade version and does not have the slot in the blade.

It also has a net and line cutting system.

With the quick-release function you can use this knife in rapid action.  

This kit also includes a diamond sharpening plate.

Primary functions: field operations, underwater operations, emergency tool, survival and combat.
