If you are looking for information regarding knife steel and loads of other information regarding knives then you cannot go past knifeinformer.com Below is some great information from Matt from Knife Informer regarding different knife steels.
In the knife industry different types of steel are created by varying the types of additive elements as well as how the blade is rolled and heated (i.e. the finishing process).
Ultimately, the different types of steel used in knife blades each exhibit varying degrees of these five key properties:
Remember, blade steel is not everything. Knife buyers should beware getting caught up in researching the perfect steel type as it is not by itself the only thing that dictates how a knife will perform. Steel analysis has become somewhat scientific that it’s easy to get caught up in the maze of statistics. Note – just because a blade is made from the premium or high-end steels listed above does not automatically mean it’s “better” than the lesser steels. The heat treatment techniques used by the manufacturer as well as the design of the blade itself play a huge role in the ultimate outcome of knife performance!
In reality, all modern steels will perform well enough for most users so consider spending more time on other aspects of the pocket knife such as how the knife handles and other features.
