DDWhy did you change your cans to be practically impossible to open. When my husband tried to open one today all he could do was open it it in some spots. Can openers do not work on them. You have extra medal on them that will NOT allow a can opener to be a back up and work. We love Progresso Soups but hate the cans. We sincerely hope that you will put your Ft Knox cans in the recycling bin.
