This model of the RAO has the “Desert” finish. The blade is black with a laser produced GeoCamo pattern. Extrema Ratio guarantees this finish to be as durable as the classic black (Testudo) finish.

The unique RAO is a macho folder that you can change into a strong fixed blade. Carry it as a folder - use it as a fixed blade. A custom designed sheath with a diamond sharpener is included. The RAO sheath is as unique as the knife - it will hold the RAO as a folder or as a fixed blade and an Extrema Ratio diamond sharpener is readily accessible in its own pocket on the front of the sheath.

Do you prefer to carry a folder but need a fixed blade? The RAO is your optimum solution.
