Blacksmithing is a primitive forging process that prevailed in the countryside before the 1980s. This craft, although primitive, is very practical; although it seems simple, it is not easy to learn.
The master blacksmith buried the cut iron material in the flaming charcoal pile and burned the iron material red. When exercising, the master holds a fiery red iron block in his left hand and places it on the anvil to beat with a small hammer in his right hand; the apprentice standing opposite, under the command of the master's hammer, raises a large hammer in order to beat it. Beat until the iron material turns from red to dark, and then put it back into the furnace to burn red, and so on, and finally forge iron tools of different sizes and curvatures, such as hoes, knives and other simple tools. After forming, it is red hot again, immersed in a pool to cool, or buried in slag ash to cool naturally. Finally, it is polished with a whetstone for sharpness.
Although the process of blacksmithing is simple, the difficulty lies in grasping the different materials, heat and quenching time. It is difficult for a blacksmith to make a living without a strong quenching skill. In addition, you need to endure high temperature and be careful not to get burned by sparks at any time.
