Extrema Ratio RAO Folder Folding Knife Review

Let’s Dive into Extrema Ratio RAO Folder Folding Knife

The Extrema Ratio RAO Folder Folding Knife isn’t just another blade; it’s a statement. Extrema Ratio, an Italian manufacturer renowned for its rugged and uncompromising tactical knives, created the RAO as a folding behemoth capable of withstanding extreme abuse. It boasts a unique locking mechanism that essentially converts it into a fixed blade, coupled with a fearsome, thick blade designed for the most demanding tasks.

I was searching for a folding knife that could bridge the gap between a convenient folder and the unyielding strength of a fixed blade. I needed something I could rely on in the backcountry for everything from preparing food to processing firewood. The Extrema Ratio RAO Folder Folding Knife promised uncompromising strength in a relatively compact package, a claim I intended to verify.

Unboxing the RAO, I was immediately struck by its heft. The knife feels substantial in hand, a testament to its robust construction and quality materials. The black anodized finish is both aesthetically pleasing and provides a durable protective layer.

I considered other “strongest folder” contenders like the Cold Steel AD-15 and the Demko AD20.5, but the RAO’s unique locking mechanism and reputation for near-indestructibility ultimately swayed my decision. The Extrema Ratio RAO Folder Folding Knife seemed to offer a level of security and reliability unmatched by other folding knives.

My initial impression was a mix of excitement and slight apprehension. The RAO is undoubtedly impressive, but its size and weight raised questions about its everyday carry practicality. However, I was eager to put it through its paces and determine if its performance justified its imposing presence.

Real-World Testing: Putting Extrema Ratio RAO Folder Folding Knife to the Test

First Use Experience

My first field test of the Extrema Ratio RAO Folder Folding Knife took place during a week-long backpacking trip in the Sierra Nevada mountains. I used it for a variety of tasks, including food preparation, shelter building, and light firewood processing. The varied terrain and weather provided a good opportunity to gauge its performance in different conditions.

The RAO performed admirably, even in the damp conditions encountered at higher elevations. The N690 blade retained its edge well, and the handle provided a secure grip, even with wet hands. Its substantial weight, while noticeable, actually contributed to its stability and control during demanding cutting tasks.

I didn’t encounter any immediate issues, although the locking mechanism initially required some familiarization. The process of inserting and tightening the locking bolt takes practice, but once mastered, it provides an unparalleled level of security. The included sheath, which securely holds the knife in both open and closed positions, proved to be a valuable addition.

Extended Use & Reliability

After several months of consistent use, the Extrema Ratio RAO Folder Folding Knife has proven to be an exceptionally durable and reliable tool. There are minimal signs of wear and tear on the blade or handle, despite rigorous use. The anodized finish has held up well, showing only minor scratches.

The locking mechanism remains as secure as day one, and the blade continues to lock up tightly with no play. I’ve primarily used a strop to maintain the edge, and it responds well to simple maintenance. The blade steel shows good corrosion resistance, requiring only occasional cleaning and oiling.

Compared to my previous EDC knives, the RAO is in a different league in terms of strength and durability. While other folders might be lighter and more convenient for everyday tasks, none offer the same level of confidence when faced with challenging situations. The Extrema Ratio RAO Folder Folding Knife is a tool you can truly rely on.

Performance & Functionality

The Extrema Ratio RAO Folder Folding Knife excels in its primary function: providing a strong, reliable cutting tool for demanding tasks.

The unique locking mechanism effectively transforms the folder into a fixed blade, eliminating any blade play and providing a secure and confident cutting experience.

One of the knife’s greatest strengths is its sheer robustness. It can handle tasks that would typically be reserved for a fixed blade, like batoning small logs or prying.

Durability & Maintenance

The Extrema Ratio RAO Folder Folding Knife is built to last. The robust construction and high-quality materials ensure that it can withstand years of hard use. With proper care and maintenance, it is likely to outlive its owner.

Maintenance is relatively simple. Regular cleaning and oiling are sufficient to keep the blade in good condition. The N690 steel is relatively easy to sharpen, and the anodized finish provides excellent corrosion resistance.

Aftermarket customization options are somewhat limited, but replacement parts are available directly from Extrema Ratio. It’s designed as a complete package, not really meant to be customized. The factory configuration really is the pinnacle of the design.
