Smith & Wesson M&P Linerlock A/O Review

First Impressions of Smith & Wesson M&P Linerlock A/O

The Smith & Wesson M&P Linerlock A/O is a multi-tool knife aimed at providing users with a combination of cutting utility and emergency preparedness. Marketed under the Smith & Wesson M&P (Military & Police) line, this assisted opening knife boasts features such as a partially serrated blade, bottle opener, belt/cord cutter, glass breaker, integrated hex wrench, signal whistle, ferro rod, and a flat end screwdriver. It seeks to be a versatile tool for everyday carry and emergency situations, all packed into a relatively compact package.

Years of working in the outdoor and tactical gear industry have taught me the importance of a reliable knife, especially one that can handle multiple tasks. I was looking for a knife to keep in my truck as part of an emergency kit – something that could cut rope, break glass if needed, and even start a fire. The advertised features of the Smith & Wesson M&P Linerlock A/O seemed to address these needs adequately.

Upon unboxing, the knife feels surprisingly solid for its price point. The black rubberized aluminum handle provides a decent grip, and the assisted opening mechanism snaps the blade into place with authority. The initial impression is that it’s a budget-friendly, all-in-one tool, but closer inspection will be required to assess its true quality and durability.

Compared to, say, a Gerber multi-tool or a dedicated Benchmade knife, the Smith & Wesson M&P Linerlock A/O appears to be a compromise between functionality and price. While the Gerber offers a more comprehensive range of tools, and the Benchmade boasts superior blade steel and construction, the Smith & Wesson knife tries to bridge the gap by offering a decent set of features at a more accessible cost. I chose this model specifically for the combination of emergency preparedness features and the Smith & Wesson brand reputation, hoping it would provide a reasonable level of reliability without breaking the bank.

My initial impression is cautiously optimistic. The knife looks the part of a practical tool, but the real test will be how it performs under stress and in real-world situations. Only through extended use will I be able to determine if the Smith & Wesson M&P Linerlock A/O is a truly valuable addition to my emergency kit or just another budget gadget.

Real-World Testing: Putting Smith & Wesson M&P Linerlock A/O to the Test

First Use Experience

My first real-world test for the Smith & Wesson M&P Linerlock A/O was during a weekend camping trip in the Appalachian Mountains. This provided an opportunity to assess its cutting ability, the utility of the integrated tools, and overall ease of use in a typical outdoor setting. I used it for tasks like preparing kindling, cutting paracord, opening food packages, and testing the fire-starting capabilities of the ferro rod.

The knife performed reasonably well in dry conditions, easily slicing through rope and cardboard. The blade’s assisted opening was reliable, although the liner lock felt a little stiff initially. However, when it started to rain, the grip became somewhat slippery despite the rubberized handle, and the blade lost some of its cutting edge after extended use on wood.

The assisted opening was a plus, allowing for one-handed deployment, which is useful when you’re holding something else. I was, however, slightly disappointed with the ferro rod. It took a considerable amount of effort to produce a spark, even with proper technique.

Extended Use & Reliability

After several months of use, the Smith & Wesson M&P Linerlock A/O has shown both strengths and weaknesses. The blade has held up reasonably well to general cutting tasks, though it requires more frequent sharpening than higher-end knives. The black oxide coating has begun to wear off in places, particularly along the edge of the blade and on the handle.

The integrated tools, like the bottle opener and hex wrench, have proven useful on occasion, but their placement makes them somewhat awkward to use. The glass breaker seems sturdy enough, but I haven’t had the (mis)fortune to test it. I have noticed the liner lock becoming slightly looser over time. This is concerning.

Compared to my primary EDC knife, a Spyderco Paramilitary 2, the Smith & Wesson M&P Linerlock A/O falls short in terms of overall quality and durability. However, considering the price difference, it’s a passable option as a backup or emergency tool. Cleaning is straightforward. A simple wipe down with a damp cloth and occasional lubrication of the pivot point is sufficient.

Breaking Down the Features of Smith & Wesson M&P Linerlock A/O

Specifications

The Smith & Wesson M&P Linerlock A/O boasts the following technical specifications:

• Blade Length: 3.5 inches (8.89cm). This provides a decent cutting surface for most tasks without being overly cumbersome.
• Closed Length: 4.88 inches (12.4cm). This size makes it easy to carry in a pocket or on a belt.
• Blade Material: 8Cr13MoV stainless steel. This is a budget-friendly steel that offers decent corrosion resistance and ease of sharpening but doesn’t hold an edge as well as higher-end steels.
• Handle Material: Black rubberized aluminum. This provides a reasonably secure grip, even in wet conditions, although it can feel a bit cheap.
• Lock Type: Linerlock. A common and generally reliable locking mechanism, though quality can vary.
• Weight: 0.38 lbs (approximately 6 ounces). Light enough for comfortable carry, yet substantial enough to feel solid.
• Additional Features: Assisted opening, bottle opener, belt/cord cutter, glass breaker, integrated hex wrench, signal whistle, ferro rod, and flat end screwdriver. These add versatility but can also compromise the knife’s primary function.
• Finish: Black oxide coating. Offers some corrosion resistance but is prone to wear.

These specifications dictate the knife’s intended use as a multi-functional tool for everyday carry and emergency preparedness. The blade steel and locking mechanism are adequate for general use, while the additional features add utility but also increase the knife’s overall complexity.

Performance & Functionality

The Smith & Wesson M&P Linerlock A/O performs adequately as a general-purpose cutting tool. The partially serrated blade is effective for cutting rope and fibrous materials, but the plain edge struggles with more demanding tasks. The assisted opening mechanism is reliable and allows for quick deployment, which can be useful in emergency situations.

The knife’s biggest strength is its versatility. The integrated tools offer a range of functionality beyond simple cutting. However, its biggest weakness is the quality of those tools. They’re not as refined or durable as dedicated tools.

The Smith & Wesson M&P Linerlock A/O almost meets expectations as an emergency tool. The combination of features is appealing, but the quality of the blade steel and the questionable durability of the locking mechanism give me pause.

Design & Ergonomics

The Smith & Wesson M&P Linerlock A/O has a utilitarian design that prioritizes function over aesthetics. The black rubberized aluminum handle provides a decent grip. The knife is relatively lightweight and comfortable to carry.

The ergonomics are acceptable but not exceptional. The placement of the integrated tools can make the knife feel bulky and awkward in the hand. The liner lock is easy to disengage. However, its long-term reliability is questionable. There is a slight learning curve to using the integrated tools effectively.

Durability & Maintenance

The long-term durability of the Smith & Wesson M&P Linerlock A/O is a concern. The blade steel is prone to dulling. The black oxide coating wears off easily. The liner lock is showing signs of loosening after only a few months of use.

Maintenance is relatively simple. Regular cleaning and lubrication are essential to prevent rust and corrosion. Sharpening the blade will be required frequently to maintain a decent cutting edge.

Accessories and Customization Options

The Smith & Wesson M&P Linerlock A/O comes with no additional accessories beyond the knife itself. Customization options are limited due to the integrated tools and the knife’s overall design.

Aftermarket grips are unlikely to fit properly. Replacement blades are not readily available. The knife is not particularly compatible with accessories from other brands.

Who Should Buy Smith & Wesson M&P Linerlock A/O?

The Smith & Wesson M&P Linerlock A/O is perfect for those who need a budget-friendly, multi-functional tool for general use and emergency preparedness. It’s a decent option for casual campers, hikers, and anyone looking for a backup knife to keep in their car or truck.

Those who need a high-quality, durable knife for demanding tasks should skip this product. This is not a suitable option for serious outdoorsmen, survivalists, or anyone who relies on their knife for critical situations.

Must-have accessories or modifications? A good quality knife sharpener is essential to maintain the blade’s cutting edge. A small container of lubricant for the pivot point and locking mechanism is also recommended.

Conclusion on Smith & Wesson M&P Linerlock A/O

The Smith & Wesson M&P Linerlock A/O is a decent, entry-level multi-tool knife that offers a range of features at an affordable price. It’s a suitable option for those who need a versatile tool for general use and emergency preparedness. However, its questionable durability and the limitations of its integrated tools make it a less desirable choice for serious outdoorsmen or anyone who relies heavily on their knife.

The price is generally justified for what you get, but don’t expect high-end performance or long-term reliability. It is what it is.

I would cautiously recommend it to someone looking for a budget-friendly, multi-functional knife for occasional use. If you need something more reliable, spend the extra money and invest in a higher-quality tool. Don’t rely on this for survival situations!
