Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion Review

The Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion Review No One Else Gives You

When I first saw the Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion, I was drawn to its understated, almost lived-in aesthetic. As a gear specialist with over a decade of experience across diverse environments – from the sterile precision of labs to the gritty realities of workshop benches and the unpredictable conditions of the field – I’ve learned that true quality often lies beneath flashy marketing. My previous EDC (Everyday Carry) knife had finally given up the ghost after years of faithful service, leaving a noticeable void in my daily routine. I needed something reliable, discreet, and capable of handling a wide range of tasks without being overly cumbersome. I considered a few other popular budget options, but their build quality felt flimsy, and their assisted opening mechanisms were often clunky. The Leek’s reputation for smooth operation and its distinctive BlackWash finish immediately piqued my interest, offering a promise of rugged sophistication. My initial impression upon holding it was one of balanced heft and solid construction, a feeling that immediately fostered a sense of confidence.

Real-World Testing: Putting Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion to the Test

First Use Experience

My testing began organically, integrating the Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion into my daily carry. I first used it for mundane tasks like opening packages and trimming errant threads from clothing, where its slim profile and sharp edge were immediately apparent. The assisted opening mechanism, a key feature that really stands out on this knife, proved incredibly responsive and smooth. Even with my hands slightly greasy from a workshop project, the flipper engaged reliably, deploying the blade with satisfying speed. There was a very brief learning curve with the pocket clip placement, as I typically prefer a deeper carry, but I quickly adjusted to its right-tip-up configuration.

Extended Use & Reliability

After several months of consistent use, the Leek has become an indispensable part of my toolkit. It has handled everything from slicing through stubborn zip ties and cutting cordage to detailed work like scraping old adhesive from surfaces and even fine-tuning small components on a workbench. The blade’s edge retention has been truly impressive; the composite construction with its D2 steel cutting edge has held up exceptionally well, requiring only a light touch-up on a ceramic rod to bring it back to razor sharpness. Despite being carried daily in various pockets, often alongside keys or loose change, the BlackWash finish has proven remarkably resilient, effectively masking minor scuffs and maintaining its aesthetic appeal. Cleaning is a breeze; a quick wipe-down with a soft cloth and occasional application of lubricant to the pivot is all that’s needed to keep it performing optimally. Compared to other assisted openers I’ve used, which often become stiff or develop blade play over time, this Kershaw model has remained remarkably solid and consistent.

Breaking Down the Features of Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion

Specifications

The Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion boasts a thoughtfully engineered set of specifications designed for practical performance. Its 3-inch blade length strikes an ideal balance, providing sufficient cutting surface for most tasks without becoming unwieldy. This size is perfect for concealed carry and fits comfortably in any pocket.

The 14C28N stainless steel used for the blade’s spine, combined with the D2 steel cutting edge, is a significant technological advancement. D2 is renowned for its exceptional hardness and edge retention, meaning it can take and hold a very sharp edge through prolonged use. The 14C28N provides excellent corrosion resistance and toughness, making the overall blade robust and reliable.

The BlackWash finish on both the blade and the stainless steel handle is more than just cosmetic; it significantly helps to hide everyday scratches and smudges, maintaining the knife’s “well-worn” look that is so appealing. The stainless steel handle itself is contoured for a comfortable and secure grip, even during extended use or when hands are less than dry.

At 4 inches when closed, it’s compact and unobtrusive. The 7-inch overall length when deployed provides good leverage for cutting tasks. The SpeedSafe® assisted opening mechanism is a standout feature, utilizing a torsion bar to help the blade open quickly and smoothly with the simple push of the convenient flipper. This is a crucial element for users who need rapid blade deployment.

The Tip-Lock secures blade when closed, adding an extra layer of safety and preventing accidental deployment in your pocket. A reversible pocket clip (offering right tip-up and left tip-down configurations) ensures versatile carry options for both right and left-handed users. Finally, a lanyard hole offers another carry or attachment possibility.

Performance & Functionality

The primary job of any knife is to cut, and the Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion excels at this with remarkable efficiency. The combination of a fine D2 cutting edge and the slim, modified drop-point blade shape makes it exceptionally capable for detailed work. I’ve found it to be precise when opening envelopes without damaging the contents, and equally adept at shaving thin strips of wood for tinder.

The real star here is the SpeedSafe® assisted opening. It’s one of the most refined assisted opening systems I’ve encountered; it’s consistently fast, reliable, and surprisingly smooth, offering that satisfying “snap” without feeling jarring or uncontrolled. This feature makes one-handed operation effortless, a significant advantage in scenarios where your other hand is occupied or less dexterous.

Durability has been a strong point. Despite its slender build, the knife feels robust, and the blade has maintained its sharpness longer than many other knives in its class. The BlackWash finish has held up surprisingly well, resisting minor abrasions and making the knife look good even after substantial use. The frame lock mechanism is secure, with absolutely no blade play when locked open, which instills confidence during heavier tasks.

Design & Ergonomics

Ken Onion’s design for the Leek is a masterclass in functional elegance. The knife’s slim profile is immediately noticeable, making it incredibly comfortable for everyday carry, whether in a formal trouser pocket or a rugged work pant. The stainless steel handle is contoured to fit the natural curve of the hand, providing a surprisingly secure grip for its size.

The BlackWash finish not only adds a unique, almost vintage aesthetic but also provides a subtle texture that enhances grip. It feels substantial and well-built without being heavy, which is a testament to its thoughtful construction. The flipper tab is well-placed and sized appropriately, making it easy to engage without being obtrusive when the blade is closed.

The reversible pocket clip is a welcome touch for accessibility, allowing users to configure it for their preferred carry style. The lanyard hole is also a practical addition for those who prefer extra security or an alternative carry method. Overall, the design prioritizes user comfort and ease of access without sacrificing an ounce of its intended functionality.

Durability & Maintenance

In my experience, the Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion is built for the long haul. The composite blade technology, combining the wear resistance of D2 with the corrosion resistance of 14C28N, suggests a blade that can withstand significant use before needing a full re-sharpening. After months of regular use, I’ve seen no signs of premature wear or degradation.

Maintenance is straightforward, which is a significant plus for any tool intended for daily use. A light oiling of the pivot mechanism keeps the assisted opening system running smoothly, and the stainless steel handle is easy to clean with a damp cloth. The BlackWash finish, as mentioned, is very forgiving and hides minor marks well, meaning less worry about cosmetic damage.

The lock-up mechanism feels very solid, and I haven’t experienced any loosening or degradation of its strength, even after repeatedly opening and closing the knife. The only potential point of concern, common to many folding knives with assisted opening, is keeping the pivot area clean from debris to ensure optimal performance of the SpeedSafe mechanism.

Accessories and Customization Options

The Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion comes with its primary accessory: a high-quality pocket clip. This clip is designed for secure attachment and allows for versatile carry orientations, which is a crucial aspect for everyday usability. The inclusion of a lanyard hole also offers an additional attachment point, though it doesn’t come with a lanyard itself.

While this particular Leek model isn’t designed for extensive hardware customization like some modular tools, its strength lies in its refined out-of-the-box functionality. However, the knife is compatible with standard aftermarket pocket clips should a user desire a different style or color, though the stock clip is excellent. The blade steel is a very high-quality combination, meaning it performs exceptionally well without the need for aftermarket coatings or modifications.

The Kershaw Leek Composite Blackwash Blade Assisted Folding Knife by Ken Onion is a complete package as is, focusing on delivering a superior user experience through its inherent design and materials rather than relying on add-ons. This focus on integrated quality is a hallmark of well-designed tools.
