1075
1075 carbon steel is most commonly used in construction of knives, cutting tools, but also springs. It contains 0,7 - 0,8% carbon, 0,4 - 0,7% manganese and trace amounts of phosphorus and sulfur. It is really easy to sharpen and you can easily achieve very high sharpness of the edge. 1075 is very tough steel with great resistance to chipping. On the other hand, 1075 steel has a very low corrosion resistance. It rusts very easily, therefore it is necessary to pay attention to proper care and maintenance. After every use, rinse the blade, wipe it clean, and oil it to prevent rust. Compared to 1095 steel, it has lower hardness and higher toughness, which makes it great choice for large knives or machetes designed for chopping and rough work.
Steel composition: 0,7 - 0,8% Carbon, 0,4 - 0,7% Manganese, traces of Phosphorus and Sulfur
