One Tool, Many Questions: The Kershaw Leek Black Serrated Assisted Folding Knife by Ken Onion

For years, my gear shed has been a testament to the idea that the right tool can transform a tedious task into a simple one. My search for a reliable, everyday carry knife that could handle a variety of duties without being cumbersome led me to the Kershaw Leek Black Serrated Assisted Folding Knife by Ken Onion. I’d heard whispers about its design and functionality, and with over a decade of putting equipment through its paces in everything from dusty workshops to rugged outdoor environments, I was eager to see if this knife lived up to its reputation. My previous go-to had finally succumbed to years of hard use, leaving a gap that needed filling with something both robust and practical.

Upon unboxing, the initial impression was one of sleek efficiency. The matte black finish, achieved through a Diamond-Like Carbon (DLC) coating, lent it a serious, understated look. It felt solid in the hand, with a satisfying heft that spoke of quality construction, yet remained remarkably slim. I had considered a few other compact folders, but the Leek’s combination of a renowned designer and a partially serrated blade for versatility caught my eye. My first thought was a simple, practical one: “This feels like it’s ready to work.”

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

First Use Experience

My initial testing grounds were primarily my workbench and around the property. I used the knife for opening stubborn packaging, trimming excess wire insulation, and even some light prying on stubborn project components. The SpeedSafe assisted opening was a notable feature; a gentle push on the flipper or thumbstud and the blade deployed with a satisfying, swift action. It felt intuitive from the first moment, requiring no fiddling or lengthy acclimatization.

One particular moment stands out: I was trying to cut through some thick, waxy twine that had been sealing a delivery crate. My old knife would have struggled, requiring sawing motions. With the Leek’s serrated section, the twine parted with surprising ease. There were no issues with dust or grit impeding the mechanism during these initial uses, and the grip, though slim, felt secure enough for controlled cuts.

Extended Use & Reliability

After several months of consistent daily carry and use, the Kershaw Leek Black Serrated Assisted Folding Knife by Ken Onion has proven itself a stalwart companion. It’s been my constant EDC, accompanying me on countless trips to the workshop, the garden, and even the occasional trail walk where it’s been employed for everything from cutting open a stubborn bag of soil to slicing through stray branches. The DLC coating has held up remarkably well, showing only the faintest signs of wear in high-contact areas, a testament to its scratch-resistant nature.

Durability has been excellent; the blade remains sharp with only occasional touch-ups on a sharpening stone, and the assisted opening mechanism continues to function flawlessly. Cleaning is straightforward – a quick wipe-down with a dry cloth or a brush to remove any debris from the pivot mechanism keeps it running smoothly. Compared to other assisted folders I’ve owned, this Kershaw model demonstrates a noticeable step up in build quality and long-term reliability, especially considering its relatively modest price point for a knife of this caliber.

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

Specifications

The Kershaw Leek Black Serrated Assisted Folding Knife by Ken Onion boasts a 3-inch blade made from high-performance Sandvik 14C28N stainless steel, a material known for its excellent edge retention and corrosion resistance. Its closed length is a compact 4 inches, making it unobtrusive in the pocket, while the overall length of 7 inches provides a comfortable grip for most tasks. The blade features a modified drop-point shape, offering both a keen edge for slicing and a fine tip for detailed work.

The handle is constructed from 410 steel and finished with the same DLC coating as the blade, ensuring durability and a sleek matte black appearance. This particular model features a partially serrated blade, ideal for tackling fibrous materials like rope or cordage, a feature I find particularly useful. The SpeedSafe ambidextrous assisted opening system is a highlight, allowing for quick and easy deployment with either hand. A secure frame lock keeps the blade firmly in place during use, while a Tip-Lock slider acts as a secondary lock, ensuring the blade stays closed when not in use. The pocket clip is reversible, offering both right-hand tip-up and left-hand tip-down carry configurations, and a lanyard slot is also present for additional carrying options.

Performance & Functionality

The primary function of any knife is to cut, and the Leek excels here. The Sandvik 14C28N steel holds an edge impressively well, even after significant use on tougher materials like cardboard and plastic packaging. The modified drop-point profile is a smart design choice; it offers enough belly for efficient slicing tasks, while the slim, acute tip provides the precision needed for more delicate operations, like scoring materials or cleaning out small crevices.

The partially serrated edge is where this specific Leek variant truly shines for EDC purposes. It chews through paracord, zip ties, and even thick cardboard with minimal effort. I’ve found it particularly useful when opening those frustrating blister packs that seem designed to resist all entry. The SpeedSafe assisted opening is consistently reliable, deploying the blade smoothly and quickly every single time, which is a critical factor for a knife intended for immediate use.

Design & Ergonomics

Ken Onion’s design for the Leek is a masterclass in form and function. The slim profile of the knife, both when open and closed, makes it incredibly comfortable to carry. It disappears into a pocket without creating an unsightly bulge, yet it feels substantial and secure when deployed. The DLC coating on both the blade and the 410 steel handle provides a pleasant grip, offering enough purchase without being overly aggressive or abrasive.

The contours of the handle are subtly designed for comfort, fitting naturally into the palm of my hand whether I’m performing light everyday tasks or more demanding cutting. The flipper tab, while small, is perfectly positioned for easy engagement with the index finger, and the thumbstud offers an alternative deployment method that feels equally accessible. The frame lock is robust and disengages smoothly, allowing for easy one-handed closing.

Durability & Maintenance

In terms of longevity, the Kershaw Leek Black Serrated Assisted Folding Knife by Ken Onion feels built to last. The combination of the Sandvik 14C28N blade steel and the hardened DLC coating means it’s highly resistant to corrosion and abrasion. Even after being exposed to occasional moisture and being tossed into toolboxes or pockets alongside keys, it shows minimal signs of wear beyond light cosmetic scuffing.

Maintenance is refreshingly simple. A quick wipe-down after use is usually sufficient. For deeper cleaning, a small brush can dislodge any grit that might accumulate around the pivot. Re-sharpening is also straightforward, and the steel takes well to my ceramic rods, allowing me to restore a razor-sharp edge relatively quickly. There are no obvious weak points that I’ve encountered; the lockup remains solid, and the assisted opening mechanism shows no signs of degradation.

Accessories and Customization Options

The Kershaw Leek Black Serrated Assisted Folding Knife by Ken Onion comes with a functional pocket clip, which, as mentioned, is reversible to accommodate various carry preferences. This simple accessory is crucial for keeping the knife securely on your person. While this particular model doesn’t come with a wide array of accessories like some specialized tools, its design lends itself well to personalization for those who desire it.

The standard lanyard slot is a thoughtful inclusion for those who prefer to attach a lanyard for added security or quicker retrieval. While Kershaw doesn’t offer extensive customization on this base model, the general Leek platform is well-supported within the aftermarket for things like custom scales or specialized pocket clips if one wishes to further tailor the knife to their specific aesthetic or functional needs.
