If you have good knives I wouldn't trade up to Cutco, but if you are in need of knives they aren't half bad. I don't have a full set of Cutco knives but I do love my "Spreader Spatula" which is my favorite when making sandwiches for a crowd, because you can easily spread mayo/mustard and then cut the sandwich with the serrated edge.

They also have a really awesome warranty and will replace just about everything. My mom buys even damaged ones at garage sales for super cheap then sends them in for warranty replacement then sells it as new on Ebay. There is definitely an aftermarket if you decide you don't want them.
