Remember when you said, "I wish you guys made a plain Leek with a stonewashed blade"?

Well, we made it.

Like other Leeks, it features a task-ready 3-inch blade, slim, easy-to-carry design, and cutting versatility. The modified drop-point blade shape makes it a good slicing knife, while the slim tip gives it excellent piercing and detail work capabilities. Built of Sandvik 14C28N high-performance stainless steel, the Leek’s blade comes razor sharp out of the box and holds its edge, too. We gave it a roughened up, stonewashed finish to hide scratches and for general cool looks. Of course, it also has SpeedSafe assisted opening for fast and easy one-handed opening. Left- or right-handed, a simple pull back on the ambidextrous flipper or push outward on the thumbstud and the Leek’s stonewashed blade is ready to go to work.

A sturdy frame lock keeps the blade open during use and a Tip-Lock slider locks it closed when folded. The pocketclip is reversible for tip-up or tip-down carry and the handle is drilled to accept a lanyard.
  • Flipper - May be used on either manual or assisted opening knives. The "flipper" is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle.
  • SpeedSafe® - Assists you to open any SpeedSafe® knife quickly and easily with a manual push on the thumbstud or pull back on the flipper; built into many Kershaw best sellers.
  • Frame Lock - A portion of the handle (the knife frame) moves behind the blade to lock it into position during use. This is a safety feature of the knife.
  • Reversible - Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.
  • Made In The USA - When you see this on one of the knives, it means it was made in their Tualatin, Oregon manufacturing facility by skilled Kershaw knifemakers.
  • Blade length: 3 in. (7.5 cm)
  • Closed length: 4 in. (10.3 cm)
  • Overall Length: 7 in. (17.9 cm)
  • Reversible (tip-up/tip-down) pocketclip

  • Handle: Blue Anodized 410 Stainless

Smitten with Leek
My main carry knife for years has been a Spyderco Delica 4 with a combo blade. I'm basically not a great fan of combo blades because they are not fun to sharpen, but the serrated part is good for cutting cord, and it seemed a good choice as an emergency weapon for the 16 months I spent in Afghanistan. Of late I have been concluding, however, that the straight-edge/drop point of a Wharncliffe style blade is best suited to the relatively light duty to which I put my EDC on normal days. The Leek is just about the same size as the Delica 4, but it is thinner and does not have the Spyderco hump-back whale bump for the opening hole. I got the blue version because I liked the color and because it had a stonewashed blade, which I find subtle and practical (it doesn't show the wear as much). I found myself much more enamored of this Blue Leek than I had hoped. The opening with the flipper is grease-slick and the blade locks perfectly in place each time. The blue aluminum is a deep dark color when clean, but as you handle it it acquires kind of a peacock-feather iridescent sheen that is beautiful in and of itself. It feels superb in my medium-sized hands, though nothing feels as sure to hold and wield as the brilliantly patterned FRN of the Delica 4. The Leek comes with a small thumbstud that seems useless to me. It is too small and awkardly positioned to be of any functional value that I can see, and the flipper mechanism works beautifully. This steel is new to me, but the knife is sharp out of the box and the blade shape should lend itself to staying that way. I wish it were as light as the Delica 4, though I guess the carbon fiber Leek could be a solution to that. Like Eric Clapton, I'm "Hard to Thrill", but this knife does the trick. (I also use and very much like a Ken Onion Wrinkle - the dog turd knife. It is also an incredibly smooth opener, and the big fat-bellied blade lends itself to crude cutting tasks as well as the Leek lends itself to more precise work. Two very different, but very fine knives.)

Excellent daily carry knife
I bought this knife for a light duty pocket knife. My son had a Kershaw with this blade style and I liked it. I liked the blue handle and it opens easily. I have arthritis and this is a must for me. My experience with Ken Onion knives has been great!
