Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion Review

The Story Behind the Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion

My search for a reliable, everyday carry (EDC) knife that could handle a diverse range of tasks, from workshop tinkering to general utility in the field, led me to the Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion. For years, I’d relied on a rotation of knives, each excelling in a specific niche but none truly being the all-rounder I craved. I needed a blade that could slice through cardboard with ease, precisely whittle wood for a makeshift repair, and still feel substantial and secure in my hand during more demanding jobs. The promise of S30V steel, renowned for its edge retention and toughness, paired with Ken Onion’s signature design, made this model a compelling prospect. I considered a few other premium EDC options, but their blade steels didn’t quite match the specifications, or their designs felt less proven for the kind of mixed-use I had in mind. Unboxing it, the weight felt reassuring, the stonewashed finish offered a pleasing, non-reflective texture, and the overall construction exuded a quiet confidence that suggested it was ready for work.

Real-World Testing: Putting the Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion to the Test

First Use Experience

My initial foray with this Kershaw began immediately in my workshop, a space filled with sawdust, metal shavings, and the constant need for a sharp edge. I tasked it with breaking down numerous cardboard boxes that had accumulated, a surprisingly effective test of its slicing capabilities. The recurved blade, a signature Ken Onion design, made short work of the thick corrugated material, requiring minimal effort and demonstrating excellent slicing geometry. Subsequently, I used it to trim some rough edges off a piece of plywood, where its ability to hold a fine edge became immediately apparent, shaving off thin curls without snagging. The SpeedSafe assisted opening was a revelation; a slight nudge of the thumb stud and the blade deployed with a satisfyingly swift and reliable action, even with slightly greasy hands from a prior project.

Extended Use & Reliability

Weeks turned into months, and the Blur S30V seamlessly integrated into my daily toolkit. It’s become my go-to for opening mail, preparing food on impromptu picnics, and even for more robust tasks like cutting through stubborn zip ties on equipment or stripping wire. The S30V blade steel has lived up to its reputation; it maintains an incredibly sharp edge through prolonged use, and I’ve only had to touch it up a couple of times with a ceramic rod. The anodized aircraft aluminum handle has proven remarkably resilient to scratches and scuffs, a testament to its durability, while the Trac-Tec grip-tape inserts offer unwavering purchase even when my hands are slick with oil or sweat. Unlike some budget knives that develop blade play or sticky openings over time, this Kershaw has remained solid and dependable, a true workhorse. Cleaning is straightforward; a quick wipe-down with a cloth usually suffices, and a bit of light oil on the pivot keeps the assisted opening mechanism running smoothly.

Breaking Down the Features of the Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion

Specifications

The Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion boasts a 3.4-inch blade length, providing ample cutting surface for a wide array of tasks without becoming unwieldy. This blade is crafted from S30V powdered stainless steel, a premium material known for its exceptional wear resistance and ability to retain an edge for extended periods. The closed length of 4.5 inches makes it comfortable and discreet to carry in a pocket or clipped to gear. Its overall length of 7.9 inches offers a substantial feel in the hand during use. The handle is constructed from 6061-T6 aircraft aluminum, which is both lightweight and incredibly strong, further enhanced by an anodized finish for durability and aesthetics. This aluminum is machined to accept Trac-Tec grip-tape inserts, a crucial feature for maintaining a secure grip in adverse conditions. The stonewash blade finish not only offers a non-reflective appearance but also helps to mask minor scratches that might occur during use.

Performance & Functionality

In terms of core functionality, the Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion excels. The S30V steel truly shines in its edge retention; I’ve used it for tasks that would quickly dull lesser steels, and it still slices cleanly. The recurve blade shape is incredibly versatile, providing excellent belly for slicing while the pointed tip pierces with surprising efficacy. The SpeedSafe assisted opening is consistently fast and reliable, making one-handed deployment a breeze, which is invaluable when your other hand is occupied or injured. Its primary job – cutting – is performed with remarkable precision and ease, making it a joy to use for everything from fine detail work to more aggressive chopping.

Design & Ergonomics

Ken Onion’s design philosophy is evident in the Blur’s comfortable ergonomics. The anodized aluminum handle feels secure and substantial in the hand, providing a solid platform for control. The Trac-Tec inserts are strategically placed, offering excellent tactile feedback and preventing slippage even during strenuous cutting motions. While the handle is primarily black, the underlying aluminum provides a cool, premium feel. The reversible pocket clip is a thoughtful touch, allowing for personal preference in carry style, whether tip-up or tip-down. The thumb stud for the assisted opening is well-placed and provides a positive purchase for deployment.

Durability & Maintenance

The Kershaw Blur S30V Black/Stonewashed Assisted Folding Knife by Ken Onion is built to last. The combination of S30V steel and 6061-T6 aluminum creates a knife that can withstand considerable abuse. I’ve dropped it on concrete (accidentally, of course) and it emerged unscathed, with no damage to the blade or handle. The anodizing on the handle seems very resistant to wear; it hasn’t shown any significant scuffing despite being carried in pockets alongside keys and coins. Maintenance is minimal; a quick wipe down is usually all that’s needed. For deeper cleaning, a small amount of specialized knife lubricant applied to the pivot ensures the SpeedSafe mechanism continues to operate flawlessly.

Accessories and Customization Options

This model comes equipped with a reversible pocket clip for customizable carry orientation. The handle is also drilled to accept a lanyard, offering another layer of security or attachment option for various environments. While no other significant accessories are included, the design is robust enough that it doesn’t need them for its primary function. The beauty of this knife lies in its self-sufficiency, though aftermarket custom scales or enhanced pocket clips are always an option for personalization.
