About these ratings

Hawley points come from W. M. Hawley's Japanese Swordsmiths (1981), the standard Western reference cataloguing over 12,000 smiths. Most recorded smiths sit at 15–20 points; only a few dozen legendary masters exceed 150.

Fujishiro grades (from Nihon Tōkō Jiten) rank workmanship from Chū saku up to Sai-jō saku, while the Tōkō Taikan valuation (Tokuno, 1977) reflects each smith's relative market standing in yen. Explore more smiths in the searchable swordsmith index.
