The Forging Process

Dynasty Forge creates blades out of two distinct processes: high-carbon raw iron (Tamahagane) and 1095 carbon steel. 
 

The Raw Materials

  

1095 Carbon Steel

 

Tamahagane

The raw iron material is hand selected to ensure an average carbon content of 1.0-1.2%. The pebble-like material is heated and hammered into a solid billet. To remove impurities and homogenize the iron, the billet is folded from 12-14 times where a large amount of material is lost and carbon content decreased. While this process is time-consuming, it produces a blade in the traditional manner with an active Hada (surface pattern). This process is distinctly different from folding and forging modern steels, as the selection of raw materials and the subsequent working of the material is much more skill and labor intensive. 

Preparing The Iron Billet

 

Dynasty Forge’s second line is made from 1095 carbon steel. This modern steel, in its processed form, approximates the carbon content the raw iron used in the Tamahagane process. However, as the metal is not folded, since it is already homogenous, there is no Hada evident.

Both types of blades are then hand-forged to shape. Through the forging process, carbon loss occurs and the final carbon content is approximately 0.7%, which is ideal for crafting a sharp yet resilient blade. The edge is clay-tempered and water-quenched to produce a defined and robust Hamon. All blades are then hand-polished on Japanese stones to a mirror-finish (equivalent to 3000 grit or more). Each blade is individually inspected by the master smith for defects and flaws. Only blades that pass this stringent inspection are allowed to leave the workshop.

Fittings for all Dynasty Forge blades are made of traditional materials. The Saya and handle are hand-carved to ensure a tight fit. As well, the Saya is lacquered (11 layers) to achieve a highly reflective polish. The Habaki is crafted from solid brass. All other fittings are made from iron or ox-horn. The Tsuka is covered in premium full-grain ray-skin and wrapped with either cotton or silk Ito.
