ABOUT THE RAO: The RAO is an unusual, "in your face" type of knife. A hybrid.

Big and tough! One owner described it as "a tank of a knife". This hybrid knife is both a folder and a fixed blade. It is a robust knife especially designed and suited for survival situations. Carry it on your belt, in your backpack, or strap it on your bug-out bag.

The RAO performs admirably in harsh environments that common folders could not endure. This rugged knife is a survival knife fitted with a strong, heavy blade and a hefty handle. This RAO has a tanto point.

The RAO includes a very reliable locking system with an extra safety device that turns the RAO into a solid, fixed blade knife. It is double locked using an ingeniously designed pin attached to the handle with an elastic lace and a spring loaded slide bar lock.

The RAO has a unique and specially designed heavy-duty combo nylon sheath that allows the knife to be carried either as a fixed blade or as a folder. The front section is for a closed knife carry with a protective flap. Behind this is an open section for carrying your RAO as a fixed blade.

Also includes an Extrema Ratio diamond sharpener in a pocket on the front of the sheath. This well-designed sheath holds the knife firmly so you cannot accidentally dislodge it. It is MOLLE compatible.

The RAO - very unique and showing Extrema Ratio's attention to detail and quality. Substantial. Functional. Do you prefer to carry a folder but need a fixed blade? The RAO is your optimum solution.
