M&P MP OTF 3.5in Automatic Folding Knives Review

First Impressions of M&P MP OTF 3.5in Automatic Folding Knives

Out-the-front (OTF) automatic knives occupy a unique space in the world of edged tools, blending tactical appeal with everyday utility. The M&P MP OTF 3.5in Automatic Folding Knives from Smith & Wesson aims to deliver this blend, offering a dual-edged spear point blade and a built-in glass breaker. It promises rapid deployment and robust construction, features highly sought after by law enforcement, first responders, and discerning everyday carriers.

I was in the market for a reliable, readily accessible knife that could serve dual purposes: a quick-deployment tool for emergency situations and a dependable cutting instrument for daily tasks. I needed something more than just a folding knife; I needed something that could be deployed one-handed, quickly and reliably, even when my fine motor skills might be compromised by stress or injury.

Upon unboxing the M&P MP OTF 3.5in Automatic Folding Knives, my initial impression was one of solid construction and practical design. The matte black stainless steel handle felt substantial in hand, and the bead-blasted blade offered a non-reflective surface. Compared to other OTF knives I’ve handled, such as models from Benchmade and Microtech, the M&P felt less refined but more robust, prioritizing durability over intricate aesthetics.

I ultimately chose the M&P due to its combination of affordability and functionality. While the Benchmade and Microtech offerings boast superior fit and finish, their price points are significantly higher. The M&P MP OTF 3.5in Automatic Folding Knives presented a compelling value proposition, promising reliable performance without breaking the bank. I was cautiously optimistic, hoping it would live up to my expectations despite its more budget-friendly price tag.

Real-World Testing: Putting M&P MP OTF 3.5in Automatic Folding Knives to the Test

First Use Experience

I first put the M&P MP OTF 3.5in Automatic Folding Knives to the test during a weekend survival skills course in a heavily wooded area. The weather was typical for the Pacific Northwest: damp, with intermittent rain. The knife saw use in various tasks, from preparing tinder for fire starting to cutting cordage for shelter building.

The assisted opening mechanism worked flawlessly, deploying the blade with a satisfying snap even with wet hands. However, the finger actuator required a deliberate and firm push, which might be challenging for those with weaker hand strength. I experienced no issues with the blade locking securely in place, both during deployment and retraction.

Extended Use & Reliability

After several months of regular carry and use, the M&P MP OTF 3.5in Automatic Folding Knives has proven to be a dependable tool, but not without a few minor drawbacks. The bead blast finish on the AUS-8 steel blade shows some signs of wear, with light scratches appearing after repeated use. The stainless steel handle, however, remains relatively unscathed.

Maintenance has been relatively simple, requiring occasional cleaning and lubrication of the blade deployment mechanism. I found that a few drops of quality gun oil applied to the blade track and actuator kept the action smooth and reliable. Compared to my experiences with higher-end OTF knives, the M&P requires slightly more frequent maintenance to maintain optimal performance. While it hasn’t outperformed any of my higher-end knives, it hasn’t disappointed either given the price point.

Breaking Down the Features of M&P MP OTF 3.5in Automatic Folding Knives

Specifications

• Blade Steel: AUS-8 steel provides a decent balance of edge retention, toughness, and corrosion resistance. This is a common steel for knives in this price range and offers adequate performance for most users.
• Blade Length: 3.5 inches strikes a good balance between cutting power and portability. This length is suitable for both everyday tasks and more demanding applications.
• Handle Material: Stainless steel provides a robust and corrosion-resistant grip. The stainless steel handle is durable, but some may find it less comfortable than textured or contoured handles.
• Closed Length: 5.2 inches makes it relatively compact for pocket carry. Its size ensures it remains easily accessible without being overly bulky.
• Weight: 0.375 lb (6 ounces) provides a solid feel without being overly heavy. Its weight gives the user a sense of quality and dependability.
• Blade Finish: Bead Blast reduces glare and provides a non-reflective surface. This finish is ideal for tactical applications.
• Handle Color: Black gives it a sleek, tactical look. The black handle makes it discrete and suitable for various professional and casual environments.
• Automatic Opening: Out-The-Front (OTF) mechanism ensures rapid deployment. This feature allows for quick and easy, one-handed blade deployment.
• Glass Breaker: Integrated glass breaker for emergency situations. This adds a valuable safety feature, enhancing its suitability for first responders and emergency preparedness.

Performance & Functionality

The M&P MP OTF 3.5in Automatic Folding Knives performs its intended function well, providing a readily accessible and capable cutting tool. The AUS-8 blade holds an edge adequately, though it requires more frequent sharpening than knives with premium steel blades. The automatic deployment mechanism is reliable, but requires a firm push to actuate.

The knife excels in tasks such as cutting rope, opening packages, and preparing kindling. However, the dual-edge blade design can be less versatile than a single-edge blade for certain tasks, such as carving wood. One improvement could be a more ergonomic handle design to enhance grip and comfort during extended use.

Design & Ergonomics

The build quality is solid for the price point, with tight tolerances and a robust feel. The stainless steel handle offers a secure grip, although it can become slippery when wet. The ergonomics are acceptable, but the handle lacks significant contouring, which could improve comfort during prolonged use.

There is a small learning curve associated with mastering the OTF deployment mechanism. However, with a few practice repetitions, one can quickly become proficient. It’s user-friendly after some initial familiarization.

Durability & Maintenance

The stainless steel construction and AUS-8 blade should provide reasonable longevity with proper care. Expect to perform regular cleaning and lubrication to maintain optimal performance. Replacement parts may be difficult to source, which is a common issue with budget-friendly knives.

Accessories and Customization Options

The M&P MP OTF 3.5in Automatic Folding Knives does not come with many accessories; it’s a fairly basic package. There are limited aftermarket customization options available specifically for this model. While the pocket clip is functional, it could benefit from being deeper carry for enhanced discretion.
