Tamahagane Steel: Properties, Characteristics and Prices

tamahagane

If traditional Japanese katanas are so renowned, it’s mainly for the quality of their tamahagane blade. These curved swords have made their reputation throughout the ages for the sharpness of their blade.

This cutting quality is largely due to the way Japanese smiths make their steel.

Tamahagane steel is very hard to produce because of the low proportion of materials present in Japan. The latter contains many mysteries to unravel to give you a good vision of the unique character of this metal.

How is tamahagane steel created?

The secret of Tamahagane steel making is well kept. The exact process is passed down from generation to generation by blacksmith families.

However, it is possible to train directly with a master if you are persuaded. Some blacksmiths open their doors to apprentices who must then dedicate themselves body and soul to the making of katana.

The training lasts about 5 years, and the apprentice can only start practicing after one or two years of observation…

The merging of layers

To begin, the blacksmith creates a special clay oven for firing. This furnace corresponds to what the Japanese ancestors used to create this same steel. It is an ancient art that has been passed down from generation to generation. This oven is called tatara.

Then layers of coal, wood and iron sand are fused into the clay vessel, and a typical black sand from the region is selected for the sand. This sand is made up of very small amounts of iron that the smith collects as it is fired. Two types of sand are actually used, namely acoma and masa.

For the selection of the sand, an expert is called “murage” in Japanese. The latter selects the best quality sands possible. This step will create the best tamahagane swords Japanese possible.

The separation of steel

After preparing all the layers, the blacksmith can now start firing the materials. He will then have to watch over the oven for 3 days and 3 consecutive nights. During the process, the steel will gradually appear as a block.

Inside the oven, the heat can reach 1800 degrees. This is the heat needed to melt all the components and give the famous Japanese steel tamahagane.

The process begins to take shape in a short time. It takes only one hour to see the fire bed appear. It is created as a result of the immersion of iron sand to the bottom of the clay oven. The smith can then use the color of the fire bed to see if the steel is ready or not.

Making tamahagane steel is hard work. In addition to the intense heat from the furnace, the blacksmith must constantly maintain the fire. He must add iron sand every ten minutes and fan the flames with an air blower.

After a few days, the tamahagane steel begins to form. The furnace must be broken to extract the precious metal. The steel is recovered from the bottom of the furnace as well as from the walls. It is on the side that the best parts of the steel are present.

The blacksmith will then select the best parts of the steel. If the latter are grayish in color, it is the hard part of the steel, with a high carbon content. White residue is considered soft.

Hocho Tetsu and Orishigane steel

Due to the complexity of creating tamahagane steel, the lesser quality parts will still be used. The creation of the tamahagane requires the efforts of several people over several days.

The recovered material is very rare and is only found in the most prestigious swords. Its scarcity has led throughout history to the recovery of the worst parts to transform them into Oroshigane steel.

Orishigane is a mixture of low quality tamahagane steel with other steels. Blacksmiths used to enrich this steel with carbon to control its sharpness and strength.

Hocho Tetsu, on the other hand, is a steel that contains very little carbon. It is used to create swords that are not very sharp. A steel with very little carbon will not be sharp but will have a good flexibility.
