Your stainless steel cutlery is composed of nickel and chromium so tightly bonded that it doesn't even oxidize (rust). While the amount is not noticeable by sight, molecules do come off. Every toxic molecule has to be handled by your liver. Nickel and chromium, in their non-organic form, are highly carcinogenic. Reduce your exposure. Switch to plastic cutlery. These are the best plastic knives and cutlery we have found. May be used everyday.
