This is my third set of these I want to give these more Stars for my review but unfortunately cannot! I initially bought a set and used them for prep at my restaurant, well I fell in love. Used consistently daily and still have not had to sharpen the original set after over 3 weeks. They are lightweight and sharp and the black color just makes them perfect. I ended up buying 2 additional sets,one for other employees to use and one for my home. My only con to this is that the company doesn't offer but one other set of knives. I wish they would sell other single knives it sets.
