1. Look at the color. The chopping board of good quality has a slightly green surface and a uniform color. The board has a firm and durable wooden texture. If the surface is dark gray, with spots or mildew, it should not be purchased.
2. Look at the rings. The center of the circle is at or near the center of the chopping board, and there are many annual rings and the density is even.
3. Look at the weight. In general, a cutting board with a thickness of 5 to 6 cm, the heavier the better the quality. Too thin is not only not durable, but also easy to shake when used.
4. Look at the size. The size should be moderate, 2 to 3 people's home to buy a diameter of about 28 cm is appropriate; 4 to 5 people can buy about 32 cm.
