We found the Kershaw 1660St to be the crème of the crop at a fair price during our comprehensive testing of a chosen group of the world’s top pocketknives. We tested less costly blades as well as knives designed for more aggressive use, but none of them came close to the Leek in terms of value. We gave the Kershaw 1660 St an award because of its practicality, durability, and affordable price.

The Kershaw 1660 St is a beautifully constructed knife. The slim blade is crafted from high-quality steel with meticulous attention to detail. The thumb or index finger can be used to activate the assisted-opening function. At any cost, its adaptability and ease of application stand out. We first tried the Leek several years ago, and we just revisited it. We are precise. Even after evaluating a few dozen more blades till now, what we discovered years ago remains true. In an apparently timeless manner, the Leek is fantastic.

Blade And Edge Integrity

The Leek’s blade is emblazoned with the name of its creator. Ken Onion, a well-known pocketknife guru (thus the “Leek” moniker… several models under Kershaw Knives has onion-themed names), approves the overall blade layout. It is tough to evaluate blade, particularly when trying to use objective terms. Sharpness is hard to evaluate in quantitative terms on its own. When you factor in the edge’s tensile strength as well as its capacity to tolerate traumatic deflection and degeneration, objective and comparable evaluation becomes nearly impossible. Quality blades, on the other hand, feel great when cutting. Sharpening a good blade is also a satisfying activity. The Leek blade’s intelligence and integrity will be seen by even the most casual user. It is a smart tool, and it shows in the user’s experience.

The Leek is a tiny, slender tool. It has a similar length to both of our Editors’ Pick winners. The length is ideal for everyday wear. In some situations, a deeper and wider blade could feel better, however for foods and fabrics, this sharp edge and short blade are ideal.

The Leek’s grip is a little too thin for regular carry as a pocket blade. With a knife of this size, extended use and hard cutting weary the hand. The blade opens with a thumb pin from either hand, just like the other blades in the test. A non-standard index finger flick can also be used to engage the aided opening spring. Superb. With an easy and effective liner lock, the blade opens easily.


Generally, mobility and aesthetics are at odds. A grip with a rounded shape in a radius wide enough to accommodate a lightly clenched fist is required for good ergonomics, particularly when the knife is utilised for long periods or heavy slicing. Carrying a blade in one’s pocket, on the other extreme, is more pleasant when the blade is thin and flat. The Leek has a slim handle with a mid-length blade. It practically vanishes from one’s pocket. The pocket clasp stops it from being tangled up in your keys and money. A lanyard can be run through the knife’s frame for additional carrying choices. We were delighted with the Leek’s versatility.

Quality Of Construction

Apart from the blade “side rolling” stated earlier, the Leek showed no incompetence in construction during either session of our usual usage. The Leek was carried, sliced, and dropped all over the test. The components, construction, and weight instilled trust in us and never let us down.


The Kershaw 1660 St is not a cheap tool. In fact, it falls practically exactly in our price range’s midpoint. However, thanks to the aided opening, a slew of utility changes (locking open and closed, customizable pocket clip), and flawless build, this is a blade that would last a long time while promoting more use. The Leek has achieved one of our bargain award badges based on its affordability, durability, and usefulness.
