Real-World Testing: Putting Ontario Knife RAT I Linerlock Foliage Folding Knife to the Test

First Use Experience

My initial testing began in my workshop, a space filled with sawdust, metal shavings, and a constant need for precise cutting. I used the RAT I to open tough cardboard packaging for new tools, trim stubborn plastic ties, and even slice through some thin plywood scraps for quick mock-ups. The knife performed admirably, its edge biting cleanly and consistently through different materials.

Subsequently, I took this folding knife on a weekend camping trip. Here, it tackled tasks like preparing kindling by shaving slivers off dry wood, cutting through various types of rope for securing gear, and even opening food packaging. The Ontario Knife RAT I Linerlock Foliage Folding Knife demonstrated its versatility, proving itself capable in both workshop and outdoor environments.

In terms of ease of use, the thumb stud provides a smooth and responsive deployment, allowing for quick access. The linerlock mechanism engaged with a satisfying click, offering a secure feeling during use. I encountered no significant learning curve; the knife felt intuitive and ready to go right out of the box.

One minor surprise during early use was how well the AUS-8 blade retained its edge, even after some fairly aggressive cutting tasks in the workshop. I had anticipated needing to sharpen it sooner, but it held up remarkably well, which was a pleasant discovery.

Extended Use & Reliability

After several weeks of consistent daily use, both in my workshop and as my primary EDC tool, the RAT I continues to impress. It has become my go-to for opening mail, breaking down boxes, and various impromptu cutting needs that arise throughout the day. Its presence is a constant reassurance that I have a capable tool at hand.

Durability has been a strong suit; there are no visible cracks, significant scuffs on the blade, or stiffness in the pivot. The foliage green handle, while showing some minor cosmetic wear from pocket carry, remains incredibly grippy and intact. The linerlock has remained solid, with no signs of loosening or failure, even after being engaged and disengaged countless times.

Maintenance has been straightforward. A quick wipe-down with a damp cloth after exposure to sawdust or grime, and an occasional drop of oil on the pivot, keeps it functioning smoothly. For sharpening, a few passes on a sharpening stone have easily brought the edge back to a razor-sharp state, which is a testament to the quality of the AUS-8 steel.

Compared to previous budget folding knives I’ve owned, this RAT I performs significantly better in terms of edge retention and lock-up security. It feels much closer to some of the mid-range knives I’ve handled, offering a level of reliability that justifies its price point.

Breaking Down the Features of Ontario Knife RAT I Linerlock Foliage Folding Knife

Specifications

The Ontario Knife RAT I Linerlock Foliage Folding Knife is specified with a 3.5-inch blade length, offering a substantial cutting surface for a wide range of tasks. Its closed length measures approximately 127 mm, making it compact enough for comfortable everyday carry in a pocket or bag. The blade is constructed from AUS-8 stainless steel, a material known for its excellent balance of edge retention, toughness, and corrosion resistance, especially in this price range.

This knife is designed with a linerlock mechanism, a common and robust locking system that provides reliable blade retention during use. The handle features a distinctive Foliage green color, contributing to its aesthetic appeal while also providing a good visual contrast in different environments. The blade finish is grey, which adds to its understated, utilitarian appearance.

The inclusion of a thumb stud on the blade facilitates one-handed opening, a crucial feature for quick deployment in the field. A lanyard hole is integrated into the handle, allowing for easy attachment to a carabiner or lanyard for added security or accessibility. The knife also comes equipped with a pocket clip, designed for secure and convenient tip-down or tip-up carry, depending on user preference.

Performance & Functionality

In its primary function as a cutting tool, the Ontario Knife RAT I Linerlock Foliage Folding Knife excels. The AUS-8 steel blade consistently delivers clean, precise cuts across various materials, from cardboard and rope to tougher organic matter. The 3.5-inch blade provides ample reach and leverage for most everyday tasks without becoming unwieldy.

The strengths of this folding knife lie in its robust build and reliable locking system. The linerlock has proven exceptionally secure during my testing, showing no sign of accidental disengagement. Its main weakness, if one can call it that, is that while AUS-8 is good, it won’t hold an edge quite as long as some premium steels like S35VN or CPM-20CV, but this is a trade-off for its affordability and ease of sharpening.

Overall, this knife not only meets but often exceeds expectations, especially when considering its accessible price point. It provides a level of performance and durability that many more expensive knives struggle to match, making it a truly solid performer for its intended use.

Design & Ergonomics

The build quality of the Ontario Knife RAT I Linerlock Foliage Folding Knife is impressive. The AUS-8 steel blade feels sturdy, and the grey finish is applied evenly. The Foliage green handle, made from a durable synthetic material, offers a comfortable and secure grip that doesn’t become slippery even when my hands are a little damp.

Ergonomically, the knife is well-designed for its purpose. The handle shape fits comfortably in my hand, providing excellent control during cutting tasks. The thumb stud is positioned well for quick, one-handed deployment, and the pocket clip is strong enough to keep the knife securely in place without being overly difficult to remove.

Practical design details include the textured surface of the handle, which enhances grip security, and the thoughtful placement of the lanyard hole and pocket clip. These elements, while seemingly minor, contribute significantly to the knife’s overall usability and user experience.

Durability & Maintenance

For a folding knife designed for daily use and moderate to heavy tasks, the Ontario Knife RAT I Linerlock Foliage Folding Knife is built to last. The AUS-8 stainless steel blade is inherently corrosion-resistant, and the grey finish provides an additional layer of protection. The robust linerlock mechanism is designed for longevity, with durable internal components.

Maintaining this knife is uncomplicated. Regular cleaning with soap and water, followed by drying and a light application of lubricant to the pivot and lock area, is generally sufficient. The blade material makes it easy to sharpen, and the overall construction means there are few intricate parts prone to failure.

While I haven’t encountered any significant failure points, consistent heavy use on very abrasive materials could eventually wear down the edge faster than harder steels. However, for its intended applications, it’s a very durable and reliable tool.

Accessories and Customization Options

The Ontario Knife RAT I Linerlock Foliage Folding Knife comes boxed, indicating it’s ready for gifting or immediate use. Key included features are the thumb stud for one-handed operation and the integrated pocket clip for convenient carry. A lanyard hole is also a standard feature, allowing for additional carrying options or tethering.

While this particular model doesn’t come with a vast array of included accessories like some other outdoor gear, its design prioritizes functionality. There isn’t much in the way of extensive customization beyond choosing how you orient the pocket clip or which lanyard you might attach to the lanyard hole. However, its straightforward design makes it a blank canvas for those who enjoy personalizing their tools.
