Like the original Extrema Ratio RAO, this version is an unusual type of knife. The RAO AVIO is still a folder but is carried as a fixed blade. The RAO AVIO double sheath has been replaced with a fixed blade sheath and you can carry it on your belt or on a MOLLE vest. The diamond sharpener that was in a pocket on the original RAO sheath is now part of a survival kit that comes with the RAO AVIO.

Big and tough! It is a robust knife especially designed and suited for outdoor survival situations. The Extrema Ratio RAO AVIO is as rugged as the first RAO and has the same strong, heavy blade and the same hefty handle. In addition, it has a kit carrying essential survival items and this gives you a complete, compact unit for coping with unusual and challenging situations. Great for camping, hunting, as well as survival.

The RAO AVIO includes a very reliable locking system with an extra safety device that turns the RAO AVIO 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 specially designed heavy-duty nylon sheath has a protective inner liner and is MOLLE compatible. This well designed sheath holds the knife securely. The sheath and kit are a dark green color, and the knife has the black (Testudo) finish.

You can carry the kit as a separate unit or attach it to the sheath. It is also MOLLE compatible and made of the same heavy-duty nylon as the sheath. This kit is small enough to carry in your cargo pocket. The RAO AVIO kit is approximately 5.5 inches long (139.70 mm), by 3.25 inches wide (82.55 mm), by 2 inches thick (50.80 mm). This kit contains: a whistle, compass, paracord, flint and striker, water purification tablets, snare wire, wire saw, light, and a diamond sharpener.

Carry the Extrema Ratio RAO AVIO in your bug-out bag or stash it with your survival gear. Great for camping/hunting/wilderness survival. If you need to hunker down, this is the knife you'll want with you. Be prepared.
