After 13 months in use the knives started to get rust spots on the blades (potting Corrosion) I purchased the 12 serving set and 5 out of the 12 started the pitting corrosion, At this point the spoons and forks do not show any pitting maybe it was a bad batch lot on the knives? Who knows? I rated one star due to the price I paid for top quality flatware. maybe the store can redeem them selves by just sending new ones in good faith?
