Frankly speaking, today there is a lot of trash on the market and it is really hard to find good knives. I tried many different modes: ceramic, stainless steel with different special coating also those that are considered self-sharpening. But the best thing I found is Japanese kitchen knives , indeed, they are high quality and reliable. I was using it for a year before I had to sharpen in for the first time. Its blade is perfect and I have no problem with slicing any products.
