Pros: Strength, Sharpness, Durability, Comfort, Ease...
Cons: TOO EXPENSIVE!!!!
First, I feel the need to disclose that I used to sell Cutco. I promise my opinion is not bias, because I am no longer trying to sell it.
I spent nearly $200 for my 'kit' despite a strong resistance to the idea of spending money to make money. However, I did make money selling Cutco. I was not as successful as others, and regardless of what my manager tried to tell me, I think that it is important to know the right people. These knives are very, very expensive.
Although I have not owned any other high quality cutlery, I have compared Cutco knives to other top name brands (Henckels, Wustoff, etc.) on demos and Cutco has always won every test.
I had the option of selling my Cutco set when I stopped doing demos. I could have made $300-$400. Although I could use the money, I wouldn't sell these knives for anything!
The most popular set we would try to sell is the Homemaker +8. (If I could afford it, I would have bought this set myself. Unfortunately, I will probably never have $800 to spend on knives!)
I use my kit everyday. I am a housewife, and I am learning to cook like a Grandma, making lots of real home made meals instead of the microwave pizzas I used to make when I first got married. So it is important to have a decent set of knives, and I am very satisfied with my set of Cutco, which I have owned for over 2 years now. The knives I use the most are the Trimmer, the Table Knife (I truly wish I had more than one) and the Spatula Spreader (one of the most useful kitchen tools to own!)
I have not been brainwashed to brag about the infamous Double D edge... I have come to love the knife's sharpness only through my own personal experience. I would warn to keep banaids nearby, these knives are sharp enough that a light brush will cut your thumb. (I have several battle wounds to prove it!)
If you can afford these knives, by all means buy them! There are financing plans available if you need them.
