Iron knives belong to the wenge-wing wood of mahogany. Because the texture of the heartwood resembles chicken wings, it is the finest wood for making, furniture, musical instruments and handicrafts. Iron knives are distributed in China's Guangdong and Guangxi provinces, and there are many Xishuangbanna in Yunnan.
The iron knife is tough and compact, and has a high burning value. For this reason, the Yi people used iron swords as their fuelwood for generations. The germination of the iron knives is very strong, so the ironwood fuelwood can be often cut. The Yi people also call the iron knife wood " sickle wood ", because the fuelwood that can be provided by an iron knife can not be limited, and it is necessary to cut the axe many times. Therefore, the family members have not suffered for the salary for the rest of their lives.
Iron knife
The iron knife is hard and hard, and the knife and axe are difficult to enter. Because the Yi people used to lack processing means, they were made into various utensils and used to burn fire.
