KS1660OL: 1660OL Leek, Olive Drab

Kershaw Knives


There are lots of very good reasons the Leek is one of the most popular Kershaws. For one thing, the slim blade is remarkably versatile. This modified drop-point blade shape gives it good slicing capabilities, while the slim tip lets it excel at piercing and detail work. The blade steel is high-performance Sandvik 14C28N stainless that sharpens to a razor edge and holds the edge for a good long time. The 3-inch blade is perfect for most day-to-day tasks. 

Leek lovers also love the fast and easy opening provided by SpeedSafe assisted opening. Whether you’re left-handed or right-handed, a simple pull back on the ambidextrous flipper or push outward on the thumbstud and the Leek’s blade is ready to go to work.

But the newest and most obvious thing about this Leek is the new olive drab handle color. The color is eye-catching and different, but also discrete. The olive drab color is fade-resistant, scratch-resistant, and permanently bonded to the anodized aluminum—so it looks good now and looks good later, too.

For safety, a locking liner keeps the blade locked 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. This slim, easy-to-carry design, with plenty of cutting versatility just may be the perfect EDC.


  • 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.
  • Liner Lock - Locks the blade open during use; one side of the knife’s steel “liner,” the steel plate to which the handle scales are attached, moves into position behind the blade to securely lock it open.
  • 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.

Cons: None
Sharp and comfortable knife
I love how this knife feels in my hands. It's very sharp and ergonomically engineered. It sits nice in my pocket, the assisted open works well and the lock is a nice feature. Did I mention it's sharp? Stupidly, I cut myself deep twice in the first two weeks of owning this thing. Every part of me, except my two thumbs missing flesh, love this knife.

I love Kershaw knives but I have to speak out against this one. First off, the blade is sharp, but not as sharp as my Kershaw Needs Work; which is funny because both knives have the same steel (Sandvik 14C28N). This started to rust in my pocket after a day which I was dumbfounded about considering my Needs Work has never rusted being in my pocket for months, if not a year by now. My hands are not the biggest, but, it's not beefy enough either.Also, this knife collects more pocket lint than any I've ever carried, which interferes with the assisted opening mechanism. The pocket clip is so tight, it actually hurts your fingers to lift it just slightly and attach it to your pants, jeans, etc. Personally, the knife is too light if you ask me. I don't believe it can withstand much heavy duty use over time. It's not a terrible knife but I know there's others which are made better. Keep this as a display in your collection instead.

This is a great little knife. Well made and it had all the things I needed for work. It had legal length, light weight and a sharp point for removing splinters( I,m a wood worker.
