Stainless steel does not mean your knife blade won't rust. What it does mean is that it will be more resistant to rust than a carbon steel. Why? Chromium content is the primary difference between stainless and carbon steels. Steel, according to The American Iron and Steel Institute (AISI), must contain a minimum of 10% chromium to be considered stainless. The chromium forms a layer of chromium oxide on the steel which aids in preventing oxygen and moisture from interacting with the steel which would cause the iron in the steel to form iron oxide, also know as rust.
So on rainy Monday's (or any other day of the week), choosing a knife like the Spyderco Persian C105GP2 with a stainless steel blade would be ideal. National Knives carries a wide variety of cutlery made with stainless steel and I would be more than happy to have you stop by my website and take a peek.
In future blogs, I will be discussing the different types of stainless steels as well as other materials used by knife makers and manufacturers.
