I have a Victorinox Pioneer, and I recently filed a little metal off the blade for some jimping. Is the already stainless steel blade still stainless?
SORRY,linda r your answer is incorrect. stainless is made by adding nickel to the steel during manufacture, the quality of the finished product is determined by the amount of nickel added. low grade stainless is magnetic. good quality stainless is not. whichever it is, it is all the way through, but the lower grades will rust.
It's solid stainless steel, stainless steel is just an alloy. You might have rubbed off some of the finish of the blade. Just polish it up if it's bothering you.
Yes, stainless steel is stainless all the way through. All metals are uniform in composition throughout the piece. However, many metal items are plated to give a different finish from the base metal or to provide protection. An example is galvanized ductwork. The duct is made of steel, but a coating of zinc is plated onto it for corrosion resistance. Likewise, some items are made of steel or brass, but are chrome plated to present a bright, shiny appearance.
Stainless steel knives, sinks, etc.may or may not be stainless steel all the way through. The question arises however, what Quality of stainless steel? For steel to be highly rust resistant, a minimum of 12% chromium must be added to the iron along with carbon (for hardness). Good food-grade stainless also is likely to contain nickel, niobium, molybdenum, and/or titanium. Victorinox has a pretty good reputation to protect so I would expect your blade is still stainless. Some good old American brand names however have been sold to marketers who outsource manufacturing to China and scrimp on the chromium and nickle content in their stainless products. That is why you can spend $50 at Lowes for a stainless steel barbeque tool set of fork, tongs, lifter etc and find them spotted with rust within a few months.
