Virtually all knives made of so-called stainless steel are in fact only rust resistant, some more so than others, but in the end, all knives do rust to some degree.
How much a knife rusts depends largely on the quantity of carbon used in the knife. Carbon is also the substance that is required to give a knife its sharp edge and to retain it.
Despite this, there is now a special knife with a blade made from Japanese H1 steel that really is stainless, even in saltwater, which is widely known to be extremely corrosive.
In this metal, the element, carbon, is largely substituted by nitrogen and the end result is a knife with a life time comparable to normal types of high-quality steel, however, the difference being that this knife does not rust at all.
Naturally, all the other metal components are also completely impervious to rust.
Rust does not only have a cosmetic effect on a blade, it also affects its performance. If rust should happen to occur on the blade of the knife, it immediately loses its sharpness even before you have used it.
The Spyderco C91 Pacific Salt is an excellent one-handed pocket knife similar in style to Spyderco’s best-selling Endura model. It is a no-nonsense, robust and functional knife, just as you would expect from Spyderco.
The blade features a round hole that makes it really easy to open using just one hand. Once open, it automatically locks into place thanks to its special back-lock system. The thumb hole here is larger than in many other Spyderco models making it easy to open with gloved hands.
This is the ideal knife for a wide range of applications: diving, fishing, off-shore, the food industry, and all other professions where rust is not desired. Product specifications:
