Edo was the sword’s age of connoisseurship: the Hon’ami appraisers, the shogunal register of famous blades of 1719, and a thriving literature turned the sword into an object of study even as it ceased to be drawn in war.
This is a katana attributed to the Chikuzen Shimosaka school, dating to the early Edo period. The blade measures 74.1cm with a sori of 1.5cm and comes with a koshirae. The blade and koshirae are described as being in good condition, suitable for both display and iaido.

The Shimosaka name began not as a single hand but as a trademark shared by a band of Echizen smiths at the dawn of the shinto era, and the designated record gathers their work under that one signature rather than parsing it into individuals. The published sources read the early inscriptions, the generic Echizen no Kuni Shimosaka and the titled Higo Daijo Fujiwara Shimosaka, as the product of a group, of which the first-generation Yasutsugu served as the representative. Born in Shimosaka village of Sakata district in Omi, Yasutsugu moved to Echizen under the patronage of Yuki Hideyasu, signing in his early years Higo no Daijo Shimosaka before his Keicho 10 to 11 summons to Edo, where he forged before Ieyasu and Hidetada and received the character Yasu and the right to cut the Tokugawa hollyhock crest on his nakago. The titled signature was carried by several Echizen hands at once, and the texts list Yasutsugu, Sadakuni and Kanenori among the smiths whose chisel movement and brush intent are too alike to part on present evidence. From this band the Echizen Yasutsugu line descended, dividing after the second generation into the Edo and Echizen Shimosaka houses, and around it formed the deep relief carving the province made its own. The school is recognized first in its steel. The forging is itame mixed with mokume that stands and opens, often flowing into nagare, carrying thick ji-nie and fine chikei, the kane taking on the blackish cast the sources name outright as Echizen-gane; the same dark, standing jihada recurs from Yasutsugu through his son, through Sadatsugu, Shigetaka and the unnamed Shimosaka hands, and the commentary returns to it as the group's signature. Over it the hamon favors a suguha to chu-suguha or shallow notare into which linked gunome and ko-gunome mix, ko-ashi and yo entering, the nie thick and gathering unevenly into rough patches, kinsuji and sunagashi streaming through, the nioiguchi tending to a sinking shizumi.
The boshi is the steadiest tell, running to a ko-maru swept in hakikake and turning back long, with a Sanpin-flavored reminiscence of the Mishina and Echizen-Seki inheritance. Yet the house is not uniform: Sadakuni works an austere suguha over an unusually refined ji with little of the blackish mokume, Sadatsugu fires the brightest, most choji-laden midare of the circle, and the third generation cleans the forging and brightens the nioiguchi toward his Edo contemporaries. Binding the registers is the carving, the deep Echizen-bori and Kinai-bori of kurikara, Fudo Myoo, bonji and gomabashi set in relief within the hi, which Sadakuni may have first supplied to Yasutsugu's blades. For the collector the school rewards reading by register rather than by a single famous holding. Yasutsugu is its summit, rated Jo-jo saku, retained smith to the shogunal house, whose Sadamune and Toshiro copies (the Namazuo, the lost Oyako, the Shishi) show his own Echizen hand under the model, and whose best katana carry the possession inscriptions of his patron Honda Hida no Kami Narishige and provenance in the Echizen and Kishu Tokugawa houses. The second generation follows so faithfully that his finest blades part from the father chiefly by the form of the character tsugu; the Edo third generation continues the suguha and ko-notare manners with a straight yakidashi and a Hojoji affinity. Around them the specialists define the edges of the idiom: Sadakuni and his quiet suguha with a pair of tanto in the Imperial Collection, Sadatsugu with his Narishige-crested cutting-test blades, and Shigetaka, the most skilled of Yasutsugu's pupils, whose chestnut-tailed kurijiri nakago and Kinai carving (the Honebami and Hossho copies among his masterworks) name him at a glance and whose finest work approaches the master. A signed Shimosaka blade, whether a titled Yasutsugu beneath the aoi-mon, a named piece by one of the band, or a Higo Daijo pre-Yasutsugu register, comes to market only from time to time, valued as the wellspring from which the Echizen Yasutsugu line and its carving tradition arose.

The NTHK’s principal certificate, issued for a blade of considerable quality. It confirms a genuine signature, or, for an unsigned (mumei) work, records the judges’ attribution to a smith or school. The paper carries a detailed worksheet with a numerical point score.
The NTHK (Nihon Tōken Hozon Kai, the Society for the Preservation of the Japanese Sword) is the oldest of Japan’s sword-appraisal bodies, founded in 1910, decades before the NBTHK. After the death of its long-serving head it divided into two successor societies, the NTHK and the NTHK-NPO, both of which continue to hold shinsa. NTHK certificates are known for a detailed worksheet that records a numerical point score alongside the judges’ written opinion, and the society is especially respected for its attribution of unsigned (mumei) work.
