Hammer with adjustable head weight

Most hammers are made of alloy steel. In the production of alloys, it is usually necessary to melt a plurality of metals and mix them in proportion, and then process them in different processes to obtain different characteristics. The entire production process consumes a lot of energy and releases a lot of carbon emissions, which has a huge impact on the environment. When you own Sar Jane at home, you no longer need to prepare other hammers to meet most daily use needs, which saves resources and reduces carbon emissions. Contributed to society.
