The Process of Blademaking


Hi-zukuri

Forging the blade to shape

The blade is forged to shape by heating in an open charcoal forge and then hammering to shape with a handheld hammer.

Rough grinding and filing

Although the blade is basically shaped in the forging, James uses a belt grinder and rough stone to remove scale, clean and true up the blade in preparation for applying the clay.

Tsuchi-oki

Placing the clay

James uses a clay mixed with carbon powder, iron filings and a small amount of ash taken from Asama Yama volcano in Japan.

A thin layer of clay is applied to the entire blade, then a thicker layer is applied to the spine of the blade, and a network of clay lines perpendicular to the edge create ashi.

Different patterns of clay create differing hamon and James has schooled himself in various hamon styles and is always working on new and more complex hamon patterns.

Yaki-ire

Quenching to harden the edge and create hamon

The blade, coated in clay, is heated in a charcoal forge and the plunged into water. The only guide here is experience and intuition!

This is the most dramatic moment in creating a blade, is the time when the steel is transformed and a blade is born. It goes without saying that this is also the time when most blades are ruined.

Adjusting the Curvature

During yaki-ire the blade curvature reverses and then returns, often changing the curvature of the blade.If the blade has too much curvature, then it can be released by hammering along the spine of the blade.

Rough Polishing

The size and main outlines of the blade are determined in the forging process, the final shaping is done using a belt grinder.

James polishes his blades using a belt grinder and fine stones. Although his polish brings out hamon very clearly, it is a smith's polish and nothing more.

Mei-kiri

Carving the Signature

The blade is now signed in Japanese kanji. Using a small chisel and hammer, James places his signature on the public side and the date on the private side. Other information is sometimes added on the private side.
