I highly recommend cutco knives accessories. My first set I bought in 1950 and kept it until 1983. That is 33 years later. I saw the newer ones, and had a representative come by and he was so impressed by the condition of my knives with constant use, that he wanted to use them for demonstration. I purchased a new set and gave him the original. I have now had my set for 28 years, and still look and work like new. These are the only two sets I have owned in 61 years. After my children were born, I purchased each of them a set which they still use to this day, and they too have purchased some of the new additions. The greatest knives ever. Thank you Cutco
