I bought these Knives direct from ronco within a week they started to RUST. I emailed three times to the company as they state they have a life time warrentee. No one asnwered my emails. SO I called today to inquire about replacing the knives and was told I had to send back all of the rusted knives along with 2.50 per knife abd they would replace them. I figured it out by the time I send them back and pay the extra money it would be cheaper just to buy a new set. What a waste and such a bad product and even worse customer service! DONT WASTE YOUR MONEY !
