Wazamono Rankings — Choosing Japanese Swords by Cutting Ability

What is Wazamono Classification — Its Historical Background

During the Edo period, there was a text called "Kaihoken-kenjaku" (懐宝剣尺) that systematically classified sword cutting ability. This classification system is a precious record that objectively evaluated the practical performance of swords, and continues to function today as an important reference standard for understanding the skill of sword smiths. Behind the establishment of wazamono classification was a transformation that the peace of the Edo period brought to sword culture. Samurai who had lost opportunities for actual combat began to systematically verify sword performance through "test cutting" (tameshigiri). Test cutting was conducted with strict procedures on straw, bamboo, and sometimes the bodies of executed criminals, and objectivity was ensured by compiling evaluations from multiple experienced practitioners. The accumulation of such knowledge came to fruition as "Kaihoken-kenjaku" and was passed down to later generations.

Saijou Oowazamono (最上大業物) — Supreme Cutting Ability

Saijou oowazamono is the pinnacle of wazamono classification, the highest rating with only a handful of smiths selected. The sword smiths selected for this grade coincide with some of the greatest masters in Japanese sword history.

• Osafune Kanemitsu (長船兼光): The foremost sword smith of Bizen Province, he produced numerous impressive ōdachi during the Nanboku-chō period, and his cutting ability received legendary acclaim.
• Sendai Kunikane (仙台国包): A master craftsman who served the Sendai domain of Ōshū, he received the highest rating through test cutting.
• Kotetsu (虎徹): A representative sword smith of the early Edo period, he elevated the Sōshū tradition to its pinnacle during the Edo period, achieving the highest realm in the harmony of practicality and beauty.

It should be noted that Masamune is known as the greatest master in Japanese sword history, but because it was transmitted as a National Treasure-class famous blade and no test cutting was performed on it, it falls outside the scope of wazamono ranking. Works of saijou oowazamono represent the pinnacle of Japanese swords not only in superior cutting ability, but also in the beauty of the hamon, the quality of the jihada, and the overall harmony. Existing examples are extremely rare, and those in good condition receive top-tier valuation in the international market.

Oowazamono (大業物) — Superior Practical Swords

Oowazamono is the grade next to saijou oowazamono and includes master smiths whose superior cutting ability was historically recognized.

• Kunihiro (国広): Known as Sōshū Kunihiro, he produced numerous practical and durable swords.
• Tadayoshi (忠吉): Active as a court sword smith for the Fukui domain of Echizen, he received high acclaim for works that combined keen cutting ability with robust construction.
• Sukehiro (助広): There were two generations; the first generation, Soboro Sukehiro, is classified as saijou oowazamono, while the second generation, Tsuda Echizen-no-kami Sukehiro (津田越前守助広), is classified as oowazamono. The second generation Sukehiro is a representative master of Osaka shintō and is known for his distinctive hamon based on toranba and highly accomplished workmanship.

Works by sword smiths classified as oowazamono have high artistic value as well as practical utility, and this grade enjoys consistently stable demand from collectors. For collectors seeking the combination of practicality and beauty, oowazamono can be said to be an ideal choice.

Yoki Wazamono (良業物) — Guarantee of Stable Quality

Yoki wazamono is the third-grade classification, encompassing numerous sword smiths known for consistently excellent cutting ability. The sword smiths of this rank do not necessarily have the highest renown, but they are reliable craftsmen whose skill at or above a certain level was historically certified through test cutting. Works classified as yoki wazamono were valued as practical swords widely beloved by samurai from the Sengoku through Edo periods. Even today, many works of yoki wazamono are available at relatively accessible price points, making them a good quality-assured option for collectors just beginning to collect Japanese swords. This grade can be said to offer an excellent balance between practicality and price.

Wazamono (業物) — Certified Practical Standard

Wazamono is the broadest classification, encompassing sword smiths whose swords demonstrated cutting ability at or above a certain standard through test cutting. It is said that hundreds of sword smiths belonged to this grade, and the majority of surviving Japanese swords fall into this category. Being certified as wazamono itself is proof of appropriate skill, an objective evaluation achieved only by swords that passed the practical test of test cutting. Even among wazamono-class swords, artistic value varies greatly depending on the period of manufacture, the sword smith, and the condition of preservation, and some works of exceptional artistic merit are included. With a wide range of prices, this grade offers options to a broad range of people from beginners to experienced collectors.

The Significance of Wazamono Ranking in Modern Times

In modern sword appraisal, comprehensive evaluation is conducted from multiple perspectives including not only cutting ability, but also artistic value, historical significance, rarity, and condition of preservation. While NBTHK authentication is considered the most authoritative standard, wazamono ranking also continues to function as important supplementary information for understanding the historical abilities and characteristics of sword smiths. If a work is by a sword smith classified as saijou oowazamono, one can verify that its practical quality was demonstrated through long historical use. This serves as an important positive factor in overall quality assessment of the sword, in addition to judgments about artistic value. The wazamono grade is a highly reliable indicator when selecting sword smiths.

The Fusion of Traditional Evaluation and Modern Appreciation

Wazamono ranking is not merely a historical relic of the Edo period, but a living evaluation standard for understanding the comprehensive abilities of sword smiths. For modern collectors as well, the wazamono grade is important reference information when selecting sword smiths, and serves as a key to understanding what technical strengths each sword smith possessed. Only when evaluation of beauty and evaluation of practicality are integrated can the true value of Japanese swords come into view. By combining knowledge of wazamono with a modern artistic appreciation, deeper understanding of swords and more fulfilling collection development becomes possible. Appreciation that fuses the perspectives of tradition and modernity can be said to be the path to approaching the essence of Japanese swords.
