I purchased our Tumbler as a stocking gift for my husband just hoping he would be able to get our great knife set where it would cut things smoothly. We couldn't be more pleased with the result. We can easily cut our meat and vegetables now without squishing them. It is a great product!

I love the Tumbler. I had started researching replacing my old knives, but this saved me that expense. Loved it so much I gave one to some friends as a birthday present.
