The quality and durability of the blades are incredible. I've been using this knife set for nearly 8 years and with regular sharpening these still perform flawlessly.  I also like that this set includes everything that I would need to prep any meal and never feel that I was missing a knife.  I have added some zwilling miyabi knives (bread knife, slicer, a second paring knife and a santoku and a boning knife) but only out of want, not need.
