This is a magnificent Katana certified NBTHK Hozon, attributed to the prestigious Ishidō school. Boasting a commanding 71.0 cm nagasa and an exceptionally deep 2.2 cm sori, this blade exhibits a graceful, tachi-like silhouette that was highly favored by high-ranking samurai during the early Edo period. The blade is mumei (unsigned), a common occurrence for high-quality blades that were shortened (o-suriage) or originally intended for high-status attribution.

The Ishidō smiths were renowned for their ability to revive the magnificent Bizen-den styles of the Kamakura period, particularly the flamboyant Ichimonji tradition. This blade showcases that mastery through a vivid and active hamon characterized by clove-shaped (choji) undulations and a clear, healthy steel texture (jihada).

Koshirae Details

The sword is housed in a refined set of traditional mountings. The saya is finished in a classic kuroro (deep black polished lacquer), offering a timeless and dignified aesthetic. The tsuka (hilt) is wrapped in a distinctive deep-green silk ito over high-grade rayskin.

The tsuba is an iron sukashi (openwork) design featuring the Imperial Chrysanthemum (Kiku) and Paulownia (Kiri) motifs, symbols of authority and honor. The kashira is crafted from a rich copper-gold alloy (suaka or shakudo) featuring a high-relief depiction of autumn grain or millet stalks, symbolizing a bountiful harvest and prosperity.

Swordsmith Background

The Ishidō school originally hailed from Omi province but gained its greatest fame in Edo (modern-day Tokyo) during the 17th century. Known as the "Edo Ishidō" lineage, these smiths—including masters like Mitsuhira and Tsunemitsu—specialized in recreating the complex, flower-like choji-midare hamon of the ancient Bizen masters. Their work was so technically proficient that many Ishidō blades were historically mistaken for authentic Kamakura-era Ichimonji works.

School History

As leaders of the Bizen-den revival in the Shinto (New Sword) era, the Ishidō school represented the pinnacle of artistic sword making in the Shogun’s capital. Their blades are characterized by a combination of visual splendor and robust construction. With a 2.2 cm curvature, this particular piece stands out as an exceptionally elegant example of the school's output, offering the presence of a battlefield weapon with the refined finish of a piece of fine art.

Bought a "Used like new" watch. Doesn't keep time
Color: Black/Black/Black/Fast-Wrap
I've had this for a few weeks. Since then, it's lost about 30 seconds. I'm not sure if it's this specific unit that has the issue or the mechanism itself. It's a shame because it's a killer looking watch.

Light, retro watch
Color: Brown/Brown/Natural
This is a light, comfortable and retro-stylish watch. A mixture of plastic, canvas, and faux-leather makes a good match for a college professor's tweed jacket with leather shoulders and elbow patches. It looks and feels cheap but it's actually a pretty good watch. Mine has a high contrast face making it easy to read. The hands have lume on them but it only glows for a few minutes. There is an indiglo feature when you press the winder so that's great. The day window is tiny and almost unreadable even with reading classes but other than that it is very functional. You can adjust the time and day independently (so you don't have to wind through 100+ hours to get the right day displayed). The winder setting to select between time and day adjust is very finicky. Fortunately you only need to adjust the day 5 times a year. The weakest part is the build quality. I'm not expecting Rolex, but the case corrodes really badly and the strap is short and the stitching failed so it fell off my wrist in about 6 months. I replaced the strap with a better one but the case corroded so badly I tossed it within a year. Other than looking cheap, poor build quality, and being thicker than I would like, I think this is a good watch.
