wonkee donkee, metal, metal alloy, steel alloy, All pocket knife blades are made of steels of various types; the primary difference being which element the steel has been alloyed with. On this page, we will address the types of alloy which blades may be made of, and what they mean.
steel alloy, alloy, what is an alloy, Remember; the term ‘steel alloy’ refers to steel to which other elements have been added during manufacture. Different elements impart different benefits into the final alloy.

Carbon steel

pocket knife, pocket knife handle, handle types, types of handle, Carbon steel is the most commonly used steel alloy, and is used in the vast majority of knife blades. Increasing a steel alloy’s carbon content hardens it considerably, making it less likely to bend, but more likely to snap.

Chromium steel

pocket knife, pocket knife handle, handle types, types of handle, Chromium steel is alloyed with chrome. This improves hardness, wear resistance, and corrosion resistance. Chromium steel is most commonly used in stainless steel manufacture.

Molybdenum steel

pocket knife, pocket knife handle, handle types, types of handle, Molybdenum steel is alloyed with the chemical element molybdenum. This is also commonly used in stainless steel manufacture, and improves corrosion resistance and tensile strength (the stress that the steel can withstand before failing).

Nickel steel

pocket knife, pocket knife handle, handle types, types of handle, Nickel steel is often used in blades which are likely to be exposed to water for long periods, such as on pocket knives designed for diving, wilderness survival and outdoor sports. The addition of nickel to a steel alloy greatly improves resistance to rust and corrosion.

Vanadium steel

pocket knife, pocket knife handle, handle types, types of handle, The addition of vanadium to a steel alloy results in a very fine grain structure. The finer the grain in a steel alloy, the greater its wear resistance. Vanadium steel is extremely durable, but will be more expensive than most other alloys.
