Q: Why Ceramic instead of steel?
The blade is extremely hard – only diamonds are harder. Expect little or no wear and tear on the blade. It will cut and cut and cut again . . .like cutting butter. The blade does not rust, spot or – Heaven forbid – pit, because it isn't made of steel. Sensitive food items such as eggs or citrus fruit will not assume a strange metallic taste from the blade. It is lightweight, thus well-balanced. It is also antimagnetic and well-suited for special usages.

Q. What are ceramic knives made of?
A. These knives are made of an advanced, high-tech ceramic called zirconium oxide (also called zirconia). This material, which is second in hardness only to diamond, was originally developed for industrial applications where metal components failed. Zirconium oxide is extremely hard, wear resistant, and chemically inert. For the technically minded, zirconium oxide has a hardness of 8.2 mohs (vs. steel at 5-6 mohs and diamond at 10 mohs).

Q. How do I sharpen ceramic knives?
A. You can resharpen your ceramic knife with a powered diamond sharpening wheel.

Q. Will a ceramic knife break or shatter if I drop it?
A. No (with the possible exception of the tip). Zirconium oxide is a very strong material. Like a forged steel knife, however, you can likely break the tip if the knife lands on the tip. Fortunately, we can repair most damaged tips.

Q. How can I damage a ceramic knife?
A. Two ways. First, you can chip the edge if you cut into bones or use on a surface such as marble. Second, you can break off the tip or snap off the handle if you use it to pry.
Please handle the blade carefully! Only wooden surfaces or the new plastic cutting boards are recommended. Surfaces of marble, glass, china or steel will impair the sharpness of the blade. Don't drop the blades on hard surface floors or use them as can openers. That's not included in their job description.

Q. How can I wash my ceramic knife and tools?
A. Ceramic knives and tools are very easy to clean with a quick wipe since food does not stick to them. Please do not wash them in the dishwasher. We do not recommend wash them in dishwasher since the dishwasher may be too rough and cause breakage .Violent motion against other objects, especially hard plates, could chip the objects and/or the ceramic knives and tools.

Q. Why are the main advantages of the ceramic products?
A.The superior hardness, superior corrosion resistance, superior erosion resistance and the superior thermal resistance, as well as the unique electrical and mechanical properties of Heqing ceramic products are the enabling factors in these key applications.

Q. Where should I store my Heqing ceramic knife and other Heqing ceramic products?
A. You can store your Heqing ceramic knife in a conventional knife block, in an in-drawer tray, or in the package.

Q. Where are Heqing ceramic products made?
A. Heqingproduces ceramic knives in Wuxi, a city in east China.

Q. How are Heqing knives made?
A. First, we mold ceramic powder into blade "blanks" using special high pressure (many tons!) presses. Special binders in the powder allow the blanks to retain their shape before sintering (or firing), which takes several days at extremely high temperatures (in excess of 1000¯ C). We then grind and polish the sintered blanks to form an edge and the final shape before attaching the handle.

Q. Which Ceramic knives are sharper than they look likes?
A. It is true that they are sharper than they look likes. Because they are made of high-tech ceramica material, which is second in hardness only to diamond, cermaic knives are harder and sharper than most metal knives. Be careful when using the ceramic knives.

Q. Do you make ceramic scissors as well?
A. We offer ceramic bladed scissors which are excellent for a variety of consumer and industrial applications.

Q. Will ceramic scissors shatter or break if I drop them? How can I damage ceramic scissors?
Ceramic scissors will not shatter when dropped. Like forged steel scissors, however, you can break the tip if the scissors land on the tip (very uncommon). You can also damage ceramic scissors by trying to cut very thick material or by trying to bend the blades. Ceramic blades are very strong, but not flexible.
