When steel is cold, the atoms that make up its atoms move around to form a solid, called a sheet, which has many properties.
When you heat the steel up, you’re making it more brittle, which means it becomes more prone to breaking.
In a process called hot forging, a small amount of hot steel can be heated up to over 600°C, and the resulting steel sheet becomes much harder than steel without the heating.
Cold steel is generally used for a variety of purposes, but one of the best uses is for cutting steel plates and cutting tools, and is a very good choice for cutting tools that require very high friction to function properly.
You can also use cold steel to make knives and cutting blades, as the hot steel helps it to adhere to your cutting edge more easily.
However, because cold steel is also used for knives and blades, it’s also very effective in cutting sharp objects.
