The Extrema Ratio RAO C is a compact folding knife deriving from the iconic RAO II.
Thanks to its structure, RAO C is a tool that, despite its small size, manages to guarantee the same qualities of robustness and reliability as its elder brother while offering better portability as well as manageability.
The handle is made of two finely crafted anodized aluminum handle scales on which Extrema Ratio applies a hard oxidation treatment, allowing the handle to be more resistant to wear and corrosion. Two steel frames help increase the strength of the handle to cope with the most demanding uses.
The opening lock mechanism is particularly resistant as it is supported by a safety system that transforms the knife into a proper fixed blade. The primary safety on the blade can be activated by raising and lowering the locking pin. A practical and rapid secondary safety system was added to guarantee the user maximum safety during use; the safety can be activated simply by moving the locking pin horizontally.
The reversible clip is designed to allow concealed carry inside the pocket, making the knife invisible from the outside. The blade is made of Böhler N690 steel hardened to 58 HRC with the classic Extrema Ratio MIL-C-13924 black finish. A shape with the profile of RAO C was laser cut to lighten the steel frames; this was then used to create a gadget that comes with the knife.
The Rao C is available in Black and Tactical Grey versions.

Add to BasketI love the Extrema Ratio knife designs and I wanted a more practical big folder from them. Like the last reviewer and what I’ve seen on YouTube the release is not slick. Certainly not with the same hand it’s being held by. The angle is weird and the mechanism graunchy. But if you reach over the top of the spine and release with the other hand it’s fine. 4 stars so far for this (only got it yesterday) but 5 stars to Heinnie and Nick who sorted out my discount codes.
This knife which I have only owned for a few days is without doubt the most problematic knife to oneself that I have ever used. Shame as the knife itself is built like a JCB, it is incredibly sharp and feels good in the hand. However when I came to try and close it depressing/sliding the release buttons on the side it was impossible, the mechanism grinded like an ancient tractor, and put my fingers in the position that they were right in the firing line for the razor sharp blade. I have other knives with a similar mechanism that are no problem, but this is a very heavy knife for this set up, then after several attempts to use the buttons which felt linked to a very inferior mechanism which creaked and groaned, the knife twisted in my hand and the blade came down on my left hand which I was using to hold it. The result was a very nasty cut on my hand and my thumb and finger which required medical treatment. I will take this information to Hennies and I am sure as I have been dealing with them for a very long time and I would thoroughly recommend for service to anyone will refund the cost, as the knife is a serious hazard.
