My husband and I received a set of 10 piece block set 30 years ago. The ones we have are still in good use. I received the 10 piece block set as a gift. I was thrilled! These are the best quality knives we have ever used. Incredible product. You won't be disappointed that your old knives don't seem to be up to par anymore.
