Glossary

Bizen tradition

One of the oldest and most prestigious schools of Japanese swordmaking, known for their distinct steel properties and hamon patterns.

Folding (steel)

The traditional process of repeatedly folding and hammering steel to create layers that strengthen the blade and create beautiful patterns.

Fuchi/Kashira

The artistic fittings that sit at the front and end of the tsuka (handle). These two pieces comprise a set and are always the work of a single artist

Habaki

Wedge shaped collar used to keep the sword from falling out of the saya and to support the tsuka. Custom made for each blade by a Master it can be gold, silver, or other metal wrapped around a copper core.

Hamon

Literally “blade patterns” it is the signature feature of the swordsmith’s art. Technically, the hamon outlines the transition between the region of the harder martensite steel at the blade’s edge and the softer pearlite steel at center and back of the sword. Functional, yet it is the aesthetic qualities of the hamon that set its artistic value. The patterns actually exist at different levels in the steel and can only be viewed fully by examination at various angles with different light. Extremely complex, hundreds of words and terms are needed to fully explain, define, and rate the hamon of a samurai sword.

Horimono

generic term for all carvings on a blade including grooves. More specifically, they usually refer to figures of legend, myth, or spiritual meaning.

Ji-hada

The grain pattern visible in the steel of the blade, formed during forging and polishing.

Katana

The long sword of the samurai. A blade measured over 24.” By decree, only a samurai could carry a katana. Strictly enforced. Since samurai was a protected “class,” offenders faced the death penalty by this breaking tradition.

Kenzen-Kado

Literally, “the Gate between Zen and the art of wielding the sword.” This is a unique feature of ataum swords. All my swords feature this and the fitting is always related to the overall theme of the sword-project. No other samurai swords in the world have this. The drawing of the sword begins when the samurai places the palm of his left hand over this spot. It is the first and last contact with the sword and thus placing a fitting here represents a physical feature of a symbolic spiritual act where the samurai fulfills the ideal of becoming one with his sword.

Kissaki

The fan-shaped area at the tip of the sword. An extremely important artistic feature, it gets special attention from the swordsmith during the forging process and from the polisher. Small, delicate, and rare polishing stones ranging up to thousands of dollars an ounce are used exclusively for the kissaki.
