Stainless? Not supposed to be. However, INFI has demonstrated very high
levels of stain resistance in many different climates. Uncoated blades have been tested for more than a year in Alaska and have made their way into the wilds of British Columbia, the High Sierras and the tropical rain forest. No rust in Alaska or British Columbia! No rust in the High Sierras, even when exposed to great quantities of blood and left in the wet grass overnight. The tropical rain forest, which has been known to rust plastic (just kidding), did offer the toughest of the environmental exposures and a light speckling of oxidation did occur but was easily removed in the field with a hand rubbing of sand and water. No pitting was reported. Now I'm sure that salt-water exposure would offer some different results. The point is that although INFI is not a stainless it is certainly not a rust aggressive steel as many of the high carbon steels have proven to be. Couple this with our coating and you've got yourself a fairly maintenance free knife.
