Generally steel is considered stainless if it contains at least 12% Chromium. The amount of Chromium is a debatable point some say 10.5% is enough for a steel to be stainless but when looking at most better quality stainless steels 12% - 14% seems to be the norm. That said Chromium is not the only element crucial to here. The quality of a kitchen knife varies considerably with the type of steel that the knife is made from. Many knives that are simply called stainless contain virtually no Carbon. Carbon is the element that allows steel to be hardened, hard steel will hold an edge better than soft steel thus providing better edge holding. Low Carbon Stainless typically has less than 0.03% Carbon, these tends to be used on inexpensive kitchen knives and other kitchen cutlery. They do not hold a very good edge and require frequent sharpening. Some telltale signs are highly shinny blades, often they are very thin and flexible knives, and commonly have serrated blades such as those seen on a bread knife.
Kitchen knives are one of those things in life that you have to spend a little money on to get something good. I'm not saying you need to go out and spend thousands of dollars on the best set there is, but you do get what you pay for. Most sub-$100 dollar sets have poor quality blades and are not built to last. It isn't until you get into the $150 to $200 dollar range that you start to see a lot of good sets of knives.
Kyocera knives were launched in Japan in 1984. Despite their highly technical production, Kyocera believe nothing can replace skilled craftsmanship and many years experience, therefore all Kyocera ceramic knives are individually ground by hand.
