KS1660CB: Ken Onion Leek with Composite Edge
Kershaw Knives
The Leek drop point blade is made of a patent pending composite steel with a spine of 14C28N fused with a cutting edge of CPM-D2. The blade design shows the interface of the two steels. The thing to consider is that, if the entire blade was made of this super steel, it would cost 2 or 3 times what this knife costs. By combining the steels this way, you get all the benefit of the D2 steel, at this fantastic price.

Sword makers have long known that the ideal blade is often a combination of different steels, each chosen for its unique properties. That’s the idea behind Kershaw’s composite blade knives, including the Composite Leek.

The two steels in Kershaw’s new composite blade knives retain their individual qualities, yet interact with each other and work in concert. The patent-pending technology that makes the modern composite blade possible delivers exactly the type of steel you need where you need it.
The Composite Leek offers the pocket-perfect size and styling of the Ken Onion Leek combined with our high-performance composite blade. It features the same two high-performance steels married in an even higher performance blade. The blade is paired with an all-stainless-steel handle for durability and good looks.

The index trigger serves both as an ambidextrous opening aid and as a finger guard when the knife is open. With a simple push on the index trigger, the closed knife quickly springs open using The Ken Onion Speed Safe torsion bar technology to propel the blade to an open and locked position. The dual thumb studs serve as the positive stop for the blade. The notched thumb ramp of the blade provides a secure placement for the index finger or thumb to rest on during use.

Please note, due to the nature of the steels involved, there is a slight visual imperfection near the tip of the blade. This does not in any way affect the performance of this knife.

Kershaw 1660CB Leek Assisted 3" Composite knife
I had ordered the same basic knife about 10-years ago, and wanted the newer version of the same knife minus the serrated edge. Now I keep one in my work uniform pants while on-duty and one in my jeans at home. As an emergency responder I've used this knife in multiple emergency situations as well, the last cutting a woman who rolled her vehicle on I-40 and was hanging upside down from her seat-belt. It's easy to carry & delploy. I love the way if fits in my pocket without being in the way because I HATE things in my pockets. The blade is as sharp as a razor blade & if it lasts like my other one, I'll use it for years to come as well.

Very Nice!
When I opened the box to this knife it felt like Christmas. The design of this knife is incredible especially the blade. It came with a very sharp edge. I thought the idea of combining the three metals was the coolest part of the knife. It has a nice locking mechanism is easy to use and can not unlock accidentally in your pocket. Overall it's a very sweet knife and i can't wait to show it off.Thanks Knife Center for bringing these quality American made products to us!

Good knife, excellent steel, takes an edge & holds it. every day carry
I had one of these Onions for 2 years. A couple weeks ago one of the grandkids stole it in the middle of the night and lost it in the pasture. I gave up on finding it and am ordering a new one. I had a custom D2 drop point that was my favorite for cleaning elk for many years, but a horse went ballistic about 15 years ago and spread the contents of my saddle bags over half the county. D2 is a great steel. It takes an edge and holds it. I can gut and skin an elk without having to touch up the blade and I have never had another steel that is as easy to sharpen that will hold an edge for that much work. I carried this knife every day for 2 years. It is a little heavy in the pocket for office work in the city, but at least I know it's there. I really dislike the safety mechanism that slips into lock in the pocket so that I can't open it immediately when I take it out. I dismantled that POS. I have never had the knife accidentally open in my pocket without the safety. I also don't like pocket clips. They take up room in the pocket and if you use them to clip to the pocket of your pants they keep the knife at the top and sitting down in a car can result in the knife being pushed out of your pocket, or they can be seen by nosey people like the security guard who tossed me out of the social security office because I didn't read the sign saying no weapons. Hey it's a 3 inch pocket knife, not a weapon. So I took the pocket clip off. The curly joint between the D2 part of the blade and the stainless steel back of the blade is really cool. The knife opens easily. The outside grips, it's really like a frame with no scales, are slick and could use a grip pattern, but I have never had the knife slip out of my hand even when cleaning with soapy water. D2 steel WILL RUST very quickly, like overnight. So keep the knife clean and dry it immediately. You will be a very happy camper until your grandkids lose it in the pasture.
