Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion Review

Getting My Hands on the Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion

For years, my toolkit has been an eclectic mix of specialized instruments and everyday workhorses, each chosen for its reliability and performance across diverse environments, from precise laboratory setups to rugged workshop benches and demanding field applications. My pursuit of dependable gear led me to the Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion. The need for a versatile, robust folding knife that could handle everything from minor workshop adjustments to quick field tasks without faltering became increasingly apparent. My previous knife, while functional, lacked the speed and the cutting prowess I required for certain fibrous materials, prompting a search for an upgrade. Upon receiving this Kershaw Blur, the initial impression was one of solid, purposeful construction; the weight felt balanced, and the anodized aluminum handle exuded a sense of durability. While I briefly considered a few other brands known for their assisted opening mechanisms, the specific combination of a partially serrated blade and Ken Onion’s design philosophy for the Blur line made this my clear choice. My immediate feeling was one of quiet satisfaction, a sense that I’d found a tool ready for the challenges ahead.


Real-World Testing: Putting Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion to the Test

First Use Experience

My initial testing began right on my workshop bench. I needed to trim some rubber gaskets and cut through a length of sturdy twine that had been used for securing equipment. The Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion deployed swiftly with a satisfying “snap” thanks to its SpeedSafe assisted opening. The partially serrated blade tackled the twine with remarkable ease, severing it in just a couple of strokes where my previous knife would have struggled. Trimming the rubber gasket was equally precise, with the recurved blade hugging the material for a clean cut.

I then took it out into the field, where I used it to strip insulation from a few electrical wires and to open a tightly sealed package containing new sensor components. The anodized aluminum handles provided a secure grip even with slightly greasy hands, and the Trac-Tec grip-tape inserts offered that extra confidence. There was no discernible learning curve; the thumb stud was intuitively placed, allowing for easy one-handed operation in both scenarios.

Over the following weeks, the knife became a constant companion for various tasks. I used it to open countless boxes in my home office, to trim errant threads from lab coats, and even for a bit of minor prying when a stubborn panel wouldn’t budge. It also saw duty in the garage, where I used it to scrape away old sealant and cut through thick zip ties. The knife performed admirably in all these varied conditions, proving its mettle.

Extended Use & Reliability

After several months of consistent, everyday use, the Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion continues to impress with its resilience. The Sandvik 14C28N stainless blade steel has resisted corrosion exceptionally well, even after being exposed to light moisture on a couple of occasions. There are no visible signs of damage, such as cracks or significant scuffs on the blade or handle, and the action remains as smooth and crisp as the day I first opened it.

Maintenance has been minimal, primarily involving occasional cleaning with a soft cloth and a light application of knife oil to the pivot. The DLC coating on the blade not only enhances its aesthetics but also seems to contribute to its resistance against scratches and wear, even after encountering various rough surfaces. Compared to some other assisted openers I’ve used, which sometimes develop blade wobble or sticky mechanisms over time, this Kershaw Blur has maintained its integrity remarkably well. Budget knives often show wear and tear far sooner, while more premium options sometimes demand more delicate handling, but this knife strikes a fantastic balance between robust performance and user-friendliness.

Breaking Down the Features of Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion

Specifications

The Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion is built with practicality and performance in mind, featuring a 3.4-inch recurve drop point blade. This blade shape is a workhorse, offering excellent slicing capabilities thanks to its generous belly and effective piercing power from its pointed tip. The choice of Sandvik 14C28N stainless blade steel is a significant advantage; it’s renowned for its excellent edge retention, hardness, and superior corrosion resistance, making it suitable for a wide array of tasks.

Further enhancing the blade’s resilience and aesthetic appeal is its black DLC (Diamond-Like Carbon) coating. This coating not only adds an extra layer of protection against corrosion but also provides a stealthy, non-reflective finish. The partially serrated edge is a crucial feature for those who frequently cut fibrous materials like rope, cord, or tough packaging tape, as the serrations grip and saw through them with less effort than a plain edge alone.

The handle is constructed from 6061-T6 anodized aluminum, a material often referred to as “aircraft aluminum” due to its common use in aerospace applications. This makes the handle exceptionally durable, lightweight, and resistant to scratches and fading. The inclusion of Trac-Tec grip-tape inserts on the handles is a thoughtful addition, significantly improving grip security even in slippery conditions.

Operationally, the knife employs Kershaw’s SpeedSafe assisted opening mechanism, activated by a thumbstud. This system utilizes a torsion bar to help the blade deploy smoothly and rapidly with a slight push, allowing for quick, one-handed opening. The locking liner mechanism ensures the blade remains securely in place when deployed, preventing accidental closure.

For carry preference, the pocketclip is reversible, offering users the choice of tip-up or tip-down carry on either side of the pocket. This versatility caters to a broad range of user preferences. Additionally, a pre-drilled lanyard hole provides another option for secure carrying or attachment.

  • Blade Length: 3.4 inches (8.6 cm) – A versatile size suitable for a multitude of tasks without being overly cumbersome.
  • Closed Length: 4.5 inches (11.4 cm) – Compact enough for comfortable pocket carry.
  • Overall Length: 7.9 inches (20 cm) – Offers a good grip and leverage for its blade length.
  • Weight: 3.9 oz. (110.6 g) – A balanced weight that feels substantial without being heavy.
  • Blade Steel: Sandvik 14C28N stainless – Excellent hardness, edge retention, and corrosion resistance.

Performance & Functionality

In practical application, the Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion excels at its primary function: cutting. The combination of the recurve blade shape and the partial serration makes it exceptionally adept at slicing through various materials. For tasks like opening cardboard boxes, cutting twine, or slicing through tough plastic packaging, the serrations bite in and make quick work of the material, while the plain edge portion of the blade offers clean cuts for finer tasks.

The SpeedSafe assisted opening is not just a gimmick; it’s a genuinely useful feature that significantly increases efficiency, especially when you need to access a cutting edge quickly. The deployment is consistently smooth and reliable, overcoming any initial resistance with a brisk flick of the wrist or a push on the thumbstud. This makes it ideal for situations where both hands might be occupied or when speed is of the essence.

One area where this knife truly shines is its versatility. I’ve used it for everything from precise trimming of a thin polymer sheet in the lab to more robust tasks like cutting through thicker electrical tape and stripping wire insulation in the workshop. The blade holds an edge remarkably well, and while it’s not designed for heavy-duty prying, it has proven capable of light prying tasks without showing immediate signs of damage, a testament to its robust build.

However, it’s important to acknowledge its limitations. While the serrations are excellent for fibrous materials, they can be trickier to sharpen than a plain edge, requiring specialized tools. Additionally, while the blade steel is excellent for corrosion resistance, no stainless steel is entirely rust-proof, so proper care is still recommended, especially in highly saline or acidic environments.

Design & Ergonomics

The design of the Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion is a clear win for functionality and user comfort. Ken Onion’s signature styling is evident, creating a knife that is both attractive and highly practical. The anodized aluminum handle feels robust and durable in the hand, and the matte black finish adds a tactical yet refined look.

The Trac-Tec inserts are a standout ergonomic feature. These textured panels are strategically placed to provide an exceptionally secure grip, reducing the likelihood of slippage during strenuous cutting tasks. Even with sweaty palms or when wearing gloves, the grip remains firm and reliable. The handle’s contouring is also well-executed, fitting comfortably in my medium-sized hand without creating hot spots, even during extended use.

The thumbstud is positioned optimally for easy engagement with the thumb, facilitating the SpeedSafe assisted opening with a natural motion. The liner lock is robust and disengages smoothly for closing, with just enough tension to feel secure. The pocket clip is also well-designed, providing good retention without being overly aggressive on fabric. The reversible nature of the clip is a thoughtful touch that caters to left-handed users or those who simply prefer a different carry orientation.

Durability & Maintenance

Durability is a strong suit for the Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion. The 6061-T6 aluminum handle is incredibly tough and resistant to the dings and scrapes that often plague lesser knives. The DLC coating on the blade provides an additional shield against wear and corrosion. After months of use, the blade still deploys smoothly, and the lock-up remains solid, showing no signs of premature wear or degradation.

Maintenance is straightforward. A quick wipe-down with a soft, dry cloth after use is usually sufficient for everyday carry. For more thorough cleaning, mild soap and water followed by a thorough drying and a tiny drop of lubricant on the pivot point will keep it in prime condition. The Sandvik 14C28N steel is relatively easy to resharpen, though the serrated portion requires a bit more care and the right tools.

Potential points of concern, while minor, include the possibility of the DLC coating eventually wearing through with extreme abrasion, though this would likely take years of heavy use. Also, like any assisted opener, the torsion bar could, in theory, fatigue over a very long lifespan, but this is uncommon with quality-built knives like this Kershaw. Overall, the construction suggests a knife that will last for many years of regular use.

Accessories and Customization Options

The Kershaw Blur Black Serrated Assisted Folding Knife by Ken Onion comes with a primary accessory: a reversible pocket clip that allows for versatile carry options, ensuring it can be positioned for either right or left-handed use, tip-up or tip-down. This simple yet effective accessory significantly enhances the user’s carrying experience.

Beyond the clip, the knife offers limited built-in customization. However, the pre-drilled lanyard hole allows users to attach lanyards, paracord loops, or other tethering devices, which can be useful for preventing loss or adding a personal touch. The anodized aluminum handles are finished in black, but Kershaw offers other Blur variants in different colors, suggesting a base platform that can be adapted aesthetically.

While the knife itself doesn’t have extensive aftermarket customization parts readily available in the way some firearms or more complex tools do, its core design is so solid that it rarely necessitates modification for its intended purpose. Users can, of course, customize the lanyard attachment if they choose to use one, or potentially explore handle treatments if they have the skills and desire for such modifications. The main “customization” comes down to how you choose to carry and maintain it.
