I was unimpressed by the Chicago Cutlery Essentials 15-Piece Block Set. I didn't think these would be the BEST quality, but I didn't expect them to be as low of quality as they were. You have special cleaning instructions with these which just make it a hassle. They rust. They aren't that sharp. You can't sharpen most of them. You can't put these in a dish washer. You are supposed to simply wipe them with a rag after use. You can't do that though because they need cleaned due to the fact that most of them are serrated. If you just wipe them down it's not going to clean them at all. So the problem when you decide to wash them with water they rust pretty quickly. You can't get the rust off. The knives aren't very sharp right from the beginning. You can't sharpen them like normal knives because of the serrated edges that's on most of them. Don't waste your money on the Chicago Cutlery Essentials 15-Piece Block Set. They are just a hassle and are very poor quality.
