Very corrosion resistant. The titanium-oxide coating is excellent.
The Tungsten DLC Leek (KS1660CKT):
DLC: Diamond Like Coating.
Hard, durable, and corrosion resistant.
The CB Leek (KS1660CB):
Composite blade Sandvik on the spine and CPM-D2 cutting edge.
The CPM-D2 is an excellent steel. It is a better cutting edge that the other 2 knives mentioned. (IMO)
This knife though will have the least corrosion resistance. You would have to put a thin oil layer on the blade just like your Skyline.
It will also be harder to sharpen than the Sandvik blades of the other 2 knives.
I own all 3 knives and have had no problems with any of them.
The leek is designed for light to medium duty use.
I use mine at work for just about anything for opening boxes to cutting zip ties. The DLC coating has not faltered.
I personaly would go for the DLC Coated blade.Originally Posted by KERSHAW WEBSITE
