Katana USA launches free sword-craft reference library

By AI, Created 5:32 PM UTC, May 18, 2026, /AGP/ – Katana USA has launched a free educational hub on Japanese swordsmanship and collecting as interest in nihonto continues to grow among U.S. buyers. The library aims to close a knowledge gap with guides on craftsmanship, authentication, and history, and it is now available online without registration.

Why it matters: - Katana USA is trying to make Japanese sword collecting easier to understand for new buyers and more useful for experienced enthusiasts. - The launch comes as the secondary market for nihonto has shown sustained price growth among U.S. collectors over the past five years. - The new hub could help buyers distinguish between production blades and authenticated antiques before spending thousands of dollars.

What happened: - Katana USA announced a free reference library on Japanese sword metallurgy, history and collecting. - The library is aimed at nihonto, the traditional Japanese blades that include antiques and modern craft pieces. - The company said the library is live now and does not require registration. - The full collection is available at Katana USA’s library.

The details: - The expanded library includes guides on tsuba, the decorative handguards used on Japanese swords. - The resource covers the major tsuba schools, including Goto, Higo, Kaneie and Shoami. - The library explains differential hardening, the process that creates the hamon or temper line. - It includes visual guides to hamon patterns such as suguha, notare and choji. - The library offers a beginner’s guide to authentication and grading through the NBTHK shinsa process. - Guides also cover Japanese sword polishing as practiced by the togishi craftsman. - The library breaks down blade anatomy, including the kissaki, boshi, nakago, kurikata and koiguchi. - Historical features in the library cover famous smiths such as Masamune and Muramasa. - The collection also touches on cultural traditions including bushido, iaido, kendo and tameshigiri test cutting. - Katana USA said the library fills a long-standing shortage of reliable English-language reference material for new buyers. - The editorial team said the goal is to bridge the gap between casual buyers and serious collectors.

Between the lines: - The launch positions Katana USA as both a retailer and an educational source in a niche market where technical knowledge affects prices. - Auction houses including Sotheby’s reported sales of authenticated Kamakura- and Muromachi-period blades through 2024 and 2025. - NBTHK shinsa certification can drive valuation premiums of five to ten times for blades that pass Hozon, Tokubetsu Hozon and Juyo grading. - The broader sword-making tradition has been rebuilt after wartime restrictions, which adds cultural weight to the collecting market. - Japan banned sword production in 1945 during the Allied occupation, and the ban was lifted in 1953. - The NBTHK was established in 1948 to preserve existing blades and promote the craft’s cultural value. - About 200 licensed swordsmiths now operate in Japan under government oversight using traditional tamahagane steel smelted from iron sand in tatara furnaces.

What’s next: - Katana USA is likely to keep expanding its editorial library as collector interest and demand for technical guidance continue. - The company’s free guides may become a starting point for buyers researching authenticity, grading and preservation before entering the market.

The bottom line: - Katana USA is betting that education will be a competitive advantage in a market where technical expertise can dramatically change what a sword is worth.
