Ryujin 65mn Spring Steel Differentially Hardened "Kengo" KatanaBe the first one to write a review
IN STOCK - LIMITED EDITION
65mn Spring steel, differentially hardened to produce a complex REAL hamon temper line. Slightly longer than usual (11.5") handle for extra leverage, extra sori for easier cutting and decked out with Ryuin's best components. Limited stock available.
65MN Spring Steel is not in itself all that expensive. It is an excellent relatively inexpensive and common steel, with the MN standing for Manganese - which aids grain structure, and contributes to hardenability, strength & wear resistance. Improves the steel (e.g., deoxidizes) during the steel's manufacturing (hot working and rolling). And for some reason, when given a propriety hand clay treatment by Ryujin, the blade turns out with a very active and prominent natural hamon!
Better still, it has a similar carbon content to 1060 and 1075 carbon steel, creating a surprisingly durable yet traditional style blade (this steel is most commonly used to make AK47 bayonets and truck springs).
Similar swords that have recent come out on the market made from 65MN Spring Steel tend to be priced between $390 to $600 depending on the fittings. In the case of the Kengo, we use the best Ryujin has to offer, with solid brass Fuchigashira, copper seppa and habaki and black iron tsuba with real gold painted hunting tiger theme.
While cosmetically the blade is extremely attractive, it has extra curvature than a normal blade. Combined with the bo-hi and this blade, which is optimized for the height and arm length of the average American, feels very comfortable one handed or two - bit is of course designed for two handed usage.
Quality wise, it is closer in quality to the Custom Katana Elite than the standard Ryujin T10 Katana, but price wise closer to the standard model. As such, and with limited stock, these are expected to sell out fast. These prices are unsustainable, you can find other listings for the exact same model for $375 and $400 - so to say $324.99 is a bargain is an understatement!
