In Nanbokuchō Chikuzen, in the shadow of the celebrated Samonji, the Kongōbyōe smiths of the Reizen district forged a darker, quieter tradition — the Yamato manner carried to Kyūshū. Signed works are exceedingly rare; most survivors are ō-suriage Nanbokuchō blades with a blackish jigane dense with chikei under a tight hoso-suguha. The Ko-Kongōbyōe masters around Sadamori hold nearly all the school’s designations; the Sue line faded toward 1600.

During the Nanbokuchō period two groups of smiths worked in Chikuzen Province: the *Samonji* line and the Kongōbyōe line, named for the temple-associated smiths from whom the lineage descends. The setsumei trace the line to the *shodai* Kongōbyōe Moritaka (初代金剛兵衛盛高) and frame this early chapter, Ko-Kongōbyōe, as the Nanbokuchō founding generations rather than the Muromachi continuation. The smiths who anchor this phase in surviving work are Moritaka himself, present in a *mumei* katana attributed to Kongō Hyōe Moritaka, and Reizei Sadamori (冷泉貞盛), called a smith of the Kongōbyōe line and traditionally traced back to Moritaka. The repeated documentary touchstone is Sadamori's signed *tantō* inscribed "Chikushū Reizei Sadamori, Shōhei 25, first month, day," dated 1370, which fixes the active period of the early line and serves as the reference against which other works are appraised. One Moritaka attribution notes an example dated *Shōhei* 4 (1349), while the bulk of work bearing his name belongs to the Muromachi period and later, which separates the early Nanbokuchō chapter described here from what follows. What the setsumei describe again and again is a *Yamato* temperament read in both *ji* and *ha*. The forging is *itame* mixed with *mokume*, often flowing toward *masame* near the edge, with the grain standing out (*hada-dachi*); *ji-nie* adheres and *chikei* enter as a relied-upon feature. The steel takes a somewhat dark, blackish *kanairo* with slight cloudiness, and a whitish *utsuri* or *shirake-utsuri* appears, conspicuously so in several of the wider katana. The temper is characteristically a narrow *suguha* or *hoso-suguha*, low in height, with a *nioiguchi* that tends toward tightness and *ko-nie*; along the *habuchi* come *hotsure*, *uchi-noke*, and a *nijūba*-like aspect, while *kinsuji* and *sunagashi* run modestly through *ji* and *ha*. The *bōshi* runs *sugu* to *ko-maru* with *hakikake* at the point, and grooves such as *bō-hi* or *futasuji-hi* are carved *kaki-nagashi*. A distinct sub-current within Sadamori's own work widens this manner: certain signed *hira-zukuri* pieces show *notare* mixed with *gunome*, abundant *ashi*, and *kuichigai-hi* in a *naginata-hi* arrangement, contrasted explicitly in one setsumei against the narrow-*suguha* dated standard. This early restraint, dark steel, *shirake* ground, and tight low *suguha* is what the records use to set Ko-Kongōbyōe apart from the later Sue-Kongōbyōe production carried into the Muromachi period. For *kantei*, the setsumei converge on a recognizable cluster: flowing *itame* leaning to *masame*, well-entered *chikei*, blackish and whitish-cast steel showing the coloration the records tie to Kyūshū work, and a narrow *suguha* whose *nioiguchi* tends to *shizumi* with *hotsure* and *uchi-noke* along the edge. Many surviving blades are *ō-suriage mumei* katana in Nanbokuchō *taihai*, broad with shallow *sori* and extended *chū-* to *ō-kissaki*, while the signed evidence sits in *tantō* and *hira-zukuri wakizashi*. Named smiths attached to this phase are Moritaka and Reizei Sadamori, the latter also written Reizen Sadamori in earlier records. On provenance, the *tantō* certified *Jūyō Bijutsuhin* in 1939 was held by Koizumi Shinji of Kanagawa, and the line is documented in references including *Imamura Oshigata* and *Nihontō Taikan*, with later attributions to Sadamori grounded on the Shōhei 25 standard.
