Kyocera uses a zirconia ceramic material of high quality in its ceramic kitchen knife blades. This ensures long lasting extreme sharpness of your knives. Zirconia ceramic is also used for applications in aerospace the motor and medical industries.
We went back to the knife shop and started our collection of Global knives. They are made of molybdenum/vanadium stainless steel and razor sharp (and I mean sharp!). On top of that, the knives are both ice-tempered and resistant to rust or staining. That silly (at first glance) dimpled handle is much more slip resistant than our more traditional knives. One of the advantages of the all in one piece construction is that there is no place for bacteria to hide in the handle or the space between the blade and handle as there is in the traditional construction. Now add a limited lifetime warranty and you have a set of knives which will last for many generations. You will want to hand wash these knives just as you do any other good cutlery. Again, be careful, they are very sharp. They maintain that edge through a lot of use and don't require frequent sharpening.
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.
