Ontario Knife RAT-5 w/Nylon Sheath 8667 Review

This is What Happened When I Used the Ontario Knife RAT-5 w/Nylon Sheath 8667

For years, I’ve relied on a diverse range of tools to navigate everything from demanding outdoor expeditions to the precise environments of a workshop and laboratory. My search for a reliable, do-it-all fixed blade knife led me to the Ontario Knife RAT-5 w/Nylon Sheath 8667. This knife, a collaboration with Jeff Randall, promised a blend of robust construction and practical design, aiming to tackle tasks from wilderness survival to everyday utility.

My previous experiences with fixed blades often involved trade-offs; either they were incredibly durable but heavy, or lighter but less robust. I needed something that wouldn’t buckle under pressure during strenuous use but also wouldn’t be an unnecessary burden when I was on the move. I considered a few other larger fixed blades, but they often lacked the refined balance or came with unnecessarily complex features.

Upon receiving the RAT-5, my first impression was one of solid, no-nonsense construction. The weight felt substantial without being cumbersome, and the micarta handle offered a reassuring grip from the outset. There was an immediate sense of confidence that this knife was built to work.

Real-World Testing: Putting Ontario Knife RAT-5 w/Nylon Sheath 8667 to the Test

First Use Experience

My initial testing began on a weekend camping trip, where the RAT-5 was immediately put to work processing firewood. I used it to split smaller kindling, baton through denser pieces, and even shave feather sticks for fire starting. The knife performed admirably, its 0.188″ thick 1095 Carbon Steel blade showing no signs of significant flexing.

Later, back in my workshop, I utilized it for more delicate tasks, like stripping wire insulation and cutting various materials for project prototyping. The plain edge, full flat taper grind proved versatile, allowing for controlled slicing without excessive material removal. The knife felt comfortable in hand through extended periods of use, and its balance made it easy to maneuver for precise cuts. I did notice the black powder coat showed some minor scuffs after repeated contact with rough wood, but this was purely cosmetic.

Extended Use & Reliability

Over several months, the Ontario Knife RAT-5 w/Nylon Sheath 8667 became a constant companion on various outings and projects. I’ve used it for field dressing small game, preparing food at campsites, and as a general utility tool around the house and workshop. The 1095 Carbon Steel has proven to be incredibly durable, holding its edge remarkably well through demanding tasks, though it does require regular sharpening to maintain peak performance.

Maintenance has been straightforward; a quick wipe-down after use and occasional oiling of the blade prevents any rust or corrosion, a common consideration with carbon steel. I’ve compared its edge retention favorably to other knives in its price bracket, though it doesn’t quite match the premium steels found in much higher-end models. The nylon sheath, while functional, has shown some wear on the stitching where it attaches to my pack, suggesting it might be a point of future failure.

Breaking Down the Features of Ontario Knife RAT-5 w/Nylon Sheath 8667

Specifications

The Ontario Knife RAT-5 w/Nylon Sheath 8667 boasts an overall length of 10 1/2 inches, with a 5-inch blade. The blade itself is crafted from 1095 Carbon Steel, known for its toughness and ease of sharpening, and it’s hardened to a Rockwell hardness of 57-59 HRC. This hardness level provides a good balance between edge retention and resistance to chipping.

The blade features a black powder coat finish for added corrosion resistance and a non-reflective surface. Its full flat taper grind is excellent for reducing drag and allowing for precise cutting. The handle is constructed from durable tan Micarta, offering a secure and comfortable grip even when wet. The knife comes with a MOLLE-compatible nylon sheath that also incorporates a Kydex insert for blade security.

Performance & Functionality

The primary function of any knife is to cut, and the RAT-5 excels in this regard. Its 5-inch blade is long enough for most utility and survival tasks, while the full flat taper grind ensures efficient cutting performance. I found it performed exceptionally well for slicing, chopping smaller branches, and general camp chores.

Its main strength lies in its versatility and robustness; it can handle heavy-duty tasks without issue. However, the black powder coat finish, while offering protection, can be prone to scratching and scuffing with aggressive use, which might be a concern for those prioritizing aesthetics. For its intended purpose, though, the performance is consistently reliable.

Design & Ergonomics

The design of the Ontario Knife RAT-5 w/Nylon Sheath 8667 is a testament to practical, user-focused engineering. The tan Micarta handle is ergonomically shaped, providing a comfortable and secure grip that minimizes hand fatigue during extended use. Its texture offers excellent purchase, even when my hands were damp or slick.

The powder-coated blade has a utilitarian look, and while it holds up reasonably well, it’s not immune to cosmetic damage. The full flat taper grind is a key design element that enhances its cutting capabilities. The overall feel of the knife is one of solid, dependable construction, with no discernible blade play or looseness in the handle.

Durability & Maintenance

Crafted from 1095 Carbon Steel, this knife is built for durability. This material is known for its toughness and ability to withstand significant stress. Under normal use, and with proper care, the Ontario Knife RAT-5 w/Nylon Sheath 8667 should last for many years.

Maintaining the carbon steel blade is crucial; regular cleaning and light oiling will prevent rust. Sharpening is straightforward due to the steel type, making it easy to restore a keen edge even in the field. The nylon sheath, while functional, appears to be the component with the lowest durability; the stitching at stress points might require reinforcement over time for heavy users.

Accessories and Customization Options

The Ontario Knife RAT-5 w/Nylon Sheath 8667 comes with a MOLLE-compatible nylon sheath. This sheath is designed to integrate with tactical gear, backpacks, and vests, offering flexible carrying options. The sheath also features a Kydex insert, which provides a secure hold for the blade and allows for quick, one-handed drawing.

While the knife itself is not highly customizable in terms of integrated features, its robust design makes it an excellent base for personalization. The Micarta handle can potentially be customized, though it’s already quite comfortable. Additional accessories that might enhance its utility include a sharpening stone for field use or paracord for creating a lanyard.

Pros and Cons of Ontario Knife RAT-5 w/Nylon Sheath 8667

Who Should Buy Ontario Knife RAT-5 w/Nylon Sheath 8667?

This knife is ideal for outdoor enthusiasts, campers, hikers, and survivalists who need a reliable tool for bushcraft, fire preparation, and general utility. It’s also a strong contender for anyone looking for a durable, no-frills fixed blade for workshop tasks or as a robust EDC (Everyday Carry) option where regulations permit. Individuals who appreciate the ease of maintenance associated with carbon steel will find this knife appealing.

Those seeking a blade that requires absolutely zero maintenance and prefers stainless steel might want to look elsewhere. Similarly, users who demand a razor-sharp, mirror-polished finish and are highly concerned with cosmetic perfection might find the utilitarian nature of the powder coat less desirable. For optimal use, carrying a sharpening stone or sharpening steel is recommended to maintain the blade’s edge on longer trips.
