The Togishi's Mastery: Revealing Grain Patterns and Perfecting the Blade Polish

Togishi: The Master Craftsmen Who Determine the Beauty of the Sword

In the process of Japanese sword creation, while the sword smith (toshin) forges steel to shape the blade, the togishi (sword polisher) is the specialized craftsman who polishes the blade and finishes it in its final aesthetic state. No matter how excellently a master smith has forged a renowned blade, if the togishi lacks skill, its true merit will not be revealed. Conversely, in the hands of a skilled togishi, even an initially unassuming sword can have its latent beauty brought forth to the maximum.

The togishi's work is not merely "polishing." It is the crystallization of refined sensibility and technique—optimizing the form and action of the hamon, the texture of the jihada, and the manifestation of the utsuri through meticulous control of the whetstones used, the polishing angle, and the subtle pressure applied.

Types of Whetstones and Polishing Stages—From Rough to Finishing

The togishi's work is broadly divided into two stages: "shitaji-togi" (base polishing) and "shiage-togi" (finish polishing).

In shitaji-togi, the togishi progresses through progressively finer whetstones while adjusting the overall shape of the blade and removing forging marks (kajiime). The primary whetstones used are as follows:

"Arato" (rough stone) is the coarsest whetstone, used for correcting blade deformation, removing large rust, and eliminating deep scratches. Artificial whetstones are often used here. "Nakato" (medium stone) removes scratches left by the arato while bringing the blade surface closer to smoothness; controlling the direction of grinding marks becomes critical at this stage. With "hosoto" (fine stone), the flatness of the blade's surface increases, and the patterns of the jihada (itame, mokume, masame, etc.) begin to appear.

Shiage-togi is the stage that represents the very essence of the togishi's art, and the choice and technique of whetstones used determine the final appearance.

"Uchigumori-to" (inner-clouded stone) is a natural whetstone from Kameoka, Kyoto, that produces a finish with uniform "cloudiness" across the entire blade. The choice of this whetstone and how it is handled reveals the togishi's level of expertise. "Hatsuyaki" is a thin whetstone chip used in the final stage of finish polishing, employed to accentuate the work of the hamon—the nie and nioi. This work determines the "brilliance" of the hamon.

The Difficult Art of Drawing Out Utsuri—A Dialogue Between Hamon and Jihada

One of the technical pinnacles of the togishi's skill is bringing out the "utsuri" (reflection). Utsuri is the whitish shadow that appears in the jigane in response to the hamon, particularly evident in Bizen-den swords. This utsuri is latent in the jigane from the forging stage, and the togishi "draws it out" through their polishing technique.

To draw out utsuri requires meticulous adjustment of polishing angle and pressure specialized for appreciating the jihada—an approach distinct from the polishing method that prioritizes hamon appreciation. A skilled togishi possesses the eye of an appraiser, asking "what should this sword reveal now?" and adjusts their polishing technique accordingly.

Utsuri comes in varieties such as "shiro-utsuri" (white reflection), "bou-utsuri" (linear reflection), and "midareu-tsuri" (turbulent reflection), and expressing each type to its fullest requires a corresponding polishing approach.

Jihada Types and Polishing—Responding to Each Pattern

Jihada refers to the pattern of forging lines that appear on the surface of the jigane, formed by the sword smith's forging technique and the properties of the steel. The togishi identifies the type of jihada and selects the optimal polishing method.

Itame-hada (straight wood grain) is the most common jihada, characterized by a flowing pattern resembling the grain of wood. It is most beautifully expressed when the entire surface is polished uniformly with uchigumori-to.

Mokume-hada (wood eye) is a rounded whorl pattern resembling tree burl, commonly seen in Bizen-den swords. To bring out this jihada, the surface "landscape" must be polished with an extremely gentle touch to avoid obscuring it.

Masame-hada (straight grain) is a jihada pattern unique to Yamato-den swords, flowing vertically in a perfectly straight direction. Polishing along the direction of the masame is fundamental; polishing against it causes the lines to collapse.

Ayasugi-hada (cedar bark grain) is a distinctive zigzag pattern found in the Gacsan lineage and is among the most technically difficult jihada types. Expressing this jihada requires specialized experience, and togishi skilled in ayasugi-hada are considered rare within the industry.

Hatsuyaki Finish—Maximizing the Work of the Hamon

The culmination of the togishi's work is the hatsuyaki finish. Hatsuyaki is a small whetstone chip manipulated with a pressing motion along the hamon, bringing into sharp relief the details within the hamon—the nie, nioi, ashi, and ha.

"Nie" (boiling) is the granular brilliance that appears within the hamon, the visible manifestation of subtle differences in carbon concentration. By adjusting how the hatsuyaki contacts the hamon, the togishi maximizes the three-dimensional quality of the nie's grains. "Nioi" (scent), finer than nie, appears as a mist-like band of light. To make nioi appear beautiful requires precise control of the hatsuyaki's pressing direction and angle.

Hatsuyaki finishing is a labor-intensive task that may take many hours for a single blade, or even several days in some cases.

The Path to Becoming a Togishi—Training and Credential Systems

To become a togishi, like a sword smith, one must apprentice under a master and undergo extensive training. The standard training period is generally 5 to 10 years, though it is not uncommon for a togishi to spend more than 10 years before being recognized as fully accomplished.

Japan's Cultural Agency administers the "Togishi Techniques Preservation" system, and togishi with exceptionally skilled technique may be designated as Important Intangible Cultural Property holders (Living National Treasures). In the modern era, individuals such as Hideo Takada are togishi recognized as Living National Treasures.

Togishi compensation varies greatly depending on the volume and quality of work and the client's needs, but typical polishing fees range from tens of thousands to hundreds of thousands of yen per blade. For polishing by renowned master togishi, fees can exceed one million yen.

Conclusion—The Togishi as a Prerequisite for Appreciation

When discussing the beauty of Japanese swords, one cannot overlook the role of the togishi. The sword smith creates latent beauty, which the togishi makes visible through polishing technique. Behind every moment a collector is moved by a blade, the togishi's work is always present.

When acquiring a fine sword, confirming its polishing history with a reliable togishi and, if necessary, requesting re-polishing contributes to the proper continuation of Japanese sword culture. The togishi, too, is an indispensable cultural custodian supporting Japanese swords as a "total art form."
