Attached to Taima-dera in the Yamato hills, the smiths of the Taima school forged under monastic patronage — and worked, like temple artisans, largely without signing. Founded by Kuniyuki in the late Kamakura and carried through the Nanbokuchō by Aritoshi, Tomokiyo, and Tomoyuki, the line survives almost entirely through unsigned blades read by kiwame. Beneath a subdued, contemplative surface the Taima hand hides a wealth of activity: a suguha tempered over standing masame, broken by hotsure, nijūba, and kuichigai-ba, lit with kinsuji and sunagashi and a hakikake bōshi ending in yakizume — restraint on the surface, brilliance within.

The Yamato Taima School (当麻) Lineage
The The Yamato Taima School (当麻), active 1280–1450 in Yamato Province across 72 documented smiths: 0 Kokuhō (National Treasures), 0 Jūbun, 0 Jūbi, 3 Tokubetsu Jūyō, 71 Jūyō.
Phase 1 · The Yamato Taima School (当麻) · 1280 – 1450
Aritoshi (有俊) — Mainline · 1264-1275. Tokujū, Jūyō. Aritoshi (有俊) is transmitted as a swordsmith of the Taima school within the Yamato tradition. The lineage encompasses two generations: the first, who signed with a two-character *mei* and whose activity is established by an extant work dated Einin 6 (1298); and the second, who signed with the three-character inscription "Naga Aritoshi" (長有俊) -- understood as an abbreviation of "Chobei no Jo Aritoshi" -- and is traditionally placed around the Kenmu era (1334-1338). Signed works by both generations are "exceedingly rare," a point the NBTHK emphasizes with remarkable consistency, and this scarcity lends each authenticated piece particular documentary value for the study of the Taima school.
The hallmark of Aritoshi's workmanship is a *suguha* temper in *ko-nie-deki* that -- "standing out even among Taima works" -- conspicuously incorporates *nijuba*, *uchi-noke*, and *kuichigai-ba*, "displaying an individualistic manner." The *jihada* is typically a tightly forged *ko-itame* or *itame* with flowing grain and a tendency toward *masame*, particularly near the cutting edge; the *shinogi-ji* is characteristically wide and the *shinogi* stands high, features that strongly express the Yamato character. Very fine *ji-nie* blankets the surface thickly, with fine *chikei* appearing throughout, and the steel is consistently described as *saeru* -- bright and clear. Along the *habuchi*, *hotsure* appears frequently, and *yubashiri* emerges "in dotted succession" in the upper portion of the blade. The *boshi* is straight, commonly finishing with vigorous *hakikake* and tending toward *yakitsume*. Within the broader Taima manner, Aritoshi is distinguished by a forging that is "comparatively tight with little *masame* tendency" relative to other Yamato attributions, and by *ha-nie* of particular brilliance.
The NBTHK reserves its strongest praise for the luminous quality of Aritoshi's *nie*: "the shining, beautiful *ha-nie* adheres well, and the *nioiguchi* is bright and clear." This interplay of thick *nie*, vigorous *nijuba*, and *kinsuji* within a fundamentally restrained *suguha* produces blades that the examiners characterize as possessing "a deeply flavored and engaging style" beneath an overall "subdued (*jimi*) impression." His work embodies the Yamato aesthetic at its most refined -- dignified, contemplative, and rich in internal activity -- while the distinctive *nijuba* serves as the primary attribution criterion that sets his oeuvre apart within the Taima lineage. The NBTHK consistently affirms that among unsigned Yamato blades displaying these combined features, "judging it to be Aritoshi is the most appropriate conclusion."
Mitsusuke (光夫) — Mainline · 1375-1379. Tokujū. Smith of the Yamato Taima School.
Nobunaga (信長) — Mainline · 1394-1428. Jūyō. Nobunaga is transmitted as a smith of the Taima group of Yamato Province who, in the early Muromachi period, relocated to Asako in Echizen. Smiths using the same name continued for several generations, and these are collectively referred to as "Asako Taima." Their workmanship resembles that of the Kaga Fujishima group, and their period of activity is said to have centered around the Oei era (1394-1428), with the line continuing into the late Muromachi period.
In terms of forging, Nobunaga's works display *itame-hada* mixed with *mokume* and *nagare-hada*, with the grain standing out and showing a somewhat darkened tone characteristic of Hokuriku workmanship alongside a Yamato temperament. The *hamon* most commonly takes the form of an angular *gunome-midare* -- the hallmark of this smith -- though works in *suguha* and *notare* are also encountered. *Ashi* and *yo* enter, *nie* adheres well, and *sunagashi* and *kinsuji* appear. The *boshi* is often executed in *hakikake*. Among the more remarkable surviving pieces, a *katakiriba-zukuri* tanto displays two distinct modes of workmanship on its opposing faces: on the *sashi-omote* a *midare* based on *gunome* mixed with "boxed" elements, and on the reverse a shallow *notare*, demonstrating Nobunaga's capacity for vigorous, open-handed work rich in *hataraki* along the *habuchi*.
Signed works by Nobunaga are rare and highly valued as documentary material. Among his well-known works is one formerly owned by Hosokawa Sansai. His tachi, though typically found in *suriage* condition, clearly display the period character of the early Muromachi era and are of good quality. The range of his extant work -- from angular *gunome-midare* pieces exhibiting the full force of the Taima-Fujishima idiom to refined *suguha* tanto in *kenzen* condition -- attests to a smith of considerable versatility whose output carries high documentary value for understanding both the Asako Taima lineage and the broader dissemination of Yamato tradition into the Hokuriku region.
Tomokiyo (友清) — Mainline · 1319-1321. Jūyō. Tomokiyo was a swordsmith of the Taima school, one of the five major groups of the Yamato tradition, which flourished from the late Kamakura period through the Nanbokucho era with Kuniyuki as its founder. Reference works state that the first-generation Tomokiyo was a son of Kuniyuki, active around the Gen'o era, and that three generations bore the same name, spanning the Ryakuo and Oei eras. The smiths of Taima-dera were originally artisans attached to the temple, which helps explain why extant signed works are exceedingly few and the majority of attributions are made on unsigned tangs. A partially inscribed tachi reading "Yamato no kuni Taima Tomo" (with the remainder cut away), designated Juyo-Token at the 13th Session, serves as the principal reference piece for this smith. A separate Nio Tomokiyo, active around the Oei era, represents a related but distinct line descended from the Yamato tradition.
In the forge, Tomokiyo's work displays *itame-hada* mixed with *mokume*, partially flowing and tending toward *masame*; fine *ji-nie* lies thickly, with frequent *chikei*, and the steel is notably clear. The *hamon* is characteristically *suguha-cho* mixed with small *gunome*, with *ashi* and *yo*; *nie* attaches thickly, and along the edge appear *hotsure*, *nijuba*, *kuichigai-ba*, and *uchi-noke*, while *kinsuji* and *sunagashi* run frequently. The *nioiguchi* is bright and clear. In these features, the Taima school's distinctive traits in both *ji* and *ha* are strongly evident. The *boshi* typically enters in *midare-komi* with vigorous *hakikake*, sometimes becoming flame-like in character.
The broad construction with ample *hiraniku* and the Enbun-Joji-type silhouette culminating in an *o-kissaki* place Tomokiyo's work firmly within the Nanbokucho period. The internal activities within the hardened edge are frequently praised as outstanding, and pieces attributed to this smith characteristically show no slackness in the *jiba*, with exceptionally good states of preservation.
Tomoyuki (友行) — Mainline · 1278-1288. Jūyō. Smith of the Yamato Taima School.
Toshinaga (俊長) — Mainline · 1352-1356. Jūyō. Smith of the Yamato Taima School.
Kuniyuki (國行) — Mainline · 1243-1247. Jūyō. Kuniyuki is regarded as the founder of the Taima group of Yamato Province and was active during the late Kamakura period. Among works of the Taima group, extant signed examples are few; only a small number survive with signatures by Kuniyuki and Aritoshi, while almost all others are works attributed as *mumei* appraisals. His two-character signature appears in two modes: one rendered in *kaisho* (formal block script) within the *kunigamae* enclosure, and another in *gyosho* (semi-cursive) form. Both varieties are considered extremely rare, and any *zaimei* tachi by this smith commands particular scholarly attention.
Kuniyuki's forging is a well-worked *itame-hada* mixed with *masame*, often showing areas of flowing grain and thick *ji-nie* with *chikei* appearing throughout. His *hamon* is typically *suguha*-based, gently *notare* and mixed with *choji* or small *gunome*, tending at times toward *ko-midare*. The *habuchi* characteristically shows *hotsure*, while within the tempered area *sunagashi* runs frequently, interspersed with *kinsuji*. The *nioiguchi* is bright and clear. His *boshi* tends toward *sugu*, turning *hakikake* or ending in *yakizume* — a disposition considered typical of Yamato workmanship. Activities such as *chikei* and *kinsuji* intermix freely, giving a lively effect to the steel.
Kuniyuki occupies a position of particular importance as the progenitor of the Taima lineage within the broader Yamato tradition. His work demonstrates the defining characteristics of Yamato-den forging — the prominent *masame* tendency, the bright and clear *ji* and *ha* described as *akaruku saeru*, and the restrained yet animated temper line — while displaying a refinement and individuality that distinguishes his hand from later Taima smiths. The rarity of signed examples only heightens the significance of each surviving blade, and his best works are noted for their *kenzen* condition and sound preservation.

Nobunaga (信長) — Mainline · 1428-1429. Smith of the Yamato Taima School.
Sueyuki (末行) — Mainline · 1394-1428. Smith of the Yamato Taima School.
Kunikiyo (國清) — Mainline · 1326-1329. Smith of the Yamato Taima School.
Kuniyuki (國行) — Mainline · 1299-1302. Kuniyuki is regarded as the founding master of the Taima school, one of the five great traditions of Yamato Province, and his activity is placed in the late Kamakura period. While sword compendia list many smiths of this group, extant signed works are exceedingly few; only a small number survive bearing signatures by Kuniyuki and Aritoshi, and most examples are *mumei* pieces identified through appraisal. The school flourished from the late Kamakura period through the Nanbokucho era, producing blades that embody the essential character of the Yamato tradition.
The construction of Kuniyuki's surviving works displays the hallmarks of Yamato craftsmanship with pronounced clarity. Wide *shinogi-ji* and a high *shinogi-suji* plainly manifest the tradition's structural principles, while the *jihada* — *itame-hada* mixed with *mokume* or *masame* — is consistently well-forged from base to tip. The *hamon* is characteristically *suguha*-based, with *hotsure* appearing along the *habuchi*, *sunagashi* and *kinsuji* intermingling to produce lively activity, and the *boshi* tending toward *hakikake* ending in *yakizume* — features the NBTHK identifies as "Yamato's traditional method." In certain works, a somewhat rough *nie* is mixed into the temper, introducing what the NBTHK describes as "an element of Soshu temperament," a quality consistent with the older attributions by the Hon'ami family for blades of this group.
Despite the rarity of signed examples, the designated works confirm Kuniyuki as a smith of genuine accomplishment. A tachi retaining a two-character signature following *suriage* is praised as displaying his characteristic features "conspicuously" and is described as "an excellent work." The *ji* and *ha* across his corpus are noted for being "bright and clear," with *chikei* and *kinsuji* interweaving to give the steel a vibrant quality. These qualities affirm the Taima school's standing among the five Yamato traditions and Kuniyuki's role as its defining voice.
Tomonaga (友長) — Mainline · 1356-1361. Smith of the Yamato Taima School.
Tomoyuki (友行) — Mainline · 1247-1249. Tomoyuki was a swordsmith of the Taima group in Yamato Province, active during the Nanbokucho period. The Taima school, taking Kuniyuki as its founder, was a lineage affiliated with Taima-dera that flourished from the mid-Kamakura period through the Nanbokucho era. One tradition holds that Tomoyuki was Kuniyuki's grandson; among his works there exists an example bearing a Bunwa-era date inscription. Signed works by the Taima group are exceptionally rare, a scarcity attributed to their dependent relationship with the temple, and the great majority of surviving pieces are unsigned blades transmitted through *kiwame* attribution.
Tomoyuki's forging characteristically shows *itame-hada* with a flowing tendency toward *nagare* and mixed *masame*, a hallmark of the Yamato tradition; *ji-nie* adheres well, with *chikei* entering, and conspicuous *nie-utsuri* appears in the better examples. The *hamon* is fundamentally *suguha-cho* with shallow *notare*, mixed with *ko-choji*, *ko-gunome*, and *gunome*; within the temper, *hotsure*, *kuichigai-ba*, and *yubashiri* occur at the edge, and *kinsuji* and *sunagashi* flash repeatedly. The *boshi* consistently shows *hakikake*, often in a *yakizume* or *yakizume*-like manner. The NBTHK setsumei observe that, in comparison with Kuniyuki, Tomoyuki's works tend to display fewer conspicuous individual characteristics; yet the best examples present thick *ha-nie* with a bright, clear brilliance and vigorous internal activities of *ashi* and *yo* that place them among the finest achievements of the school.
The attribution to Tomoyuki is typically supported by the combination of wide *mihaba* and an extended or elongated *kissaki* together with Yamato-tradition forging characteristics. Most surviving pieces are greatly shortened katana in *shinogi-zukuri*, though a *kanmuri-otoshi* tanto displaying the school's characteristic pairing of *naginata-hi* with *soe-hi* also attests to the range of his work.

当麻
The Yamato Taima School
Attached to Taima-dera in the Yamato hills, the smiths of the Taima school forged under monastic patronage — and worked, like temple artisans, largely without signing. Founded by Kuniyuki in the late Kamakura and carried through the Nanbokuchō by Aritoshi, Tomokiyo, and Tomoyuki, the line survives almost entirely through unsigned blades read by kiwame. Beneath a subdued, contemplative surface the Taima hand hides a wealth of activity: a suguha tempered over standing masame, broken by hotsure, nijūba, and kuichigai-ba, lit with kinsuji and sunagashi and a hakikake bōshi ending in yakizume — restraint on the surface, brilliance within.

The Yamato Taima School (当麻) Lineage
The The Yamato Taima School (当麻), active 1280–1450 in Yamato Province across 72 documented smiths: 0 Kokuhō (National Treasures), 0 Jūbun, 0 Jūbi, 3 Tokubetsu Jūyō, 71 Jūyō.
Phase 1 · The Yamato Taima School (当麻) · 1280 – 1450
Aritoshi (有俊) — Mainline · 1264-1275. Tokujū, Jūyō. Aritoshi (有俊) is transmitted as a swordsmith of the Taima school within the Yamato tradition. The lineage encompasses two generations: the first, who signed with a two-character *mei* and whose activity is established by an extant work dated Einin 6 (1298); and the second, who signed with the three-character inscription "Naga Aritoshi" (長有俊) -- understood as an abbreviation of "Chobei no Jo Aritoshi" -- and is traditionally placed around the Kenmu era (1334-1338). Signed works by both generations are "exceedingly rare," a point the NBTHK emphasizes with remarkable consistency, and this scarcity lends each authenticated piece particular documentary value for the study of the Taima school.
The hallmark of Aritoshi's workmanship is a *suguha* temper in *ko-nie-deki* that -- "standing out even among Taima works" -- conspicuously incorporates *nijuba*, *uchi-noke*, and *kuichigai-ba*, "displaying an individualistic manner." The *jihada* is typically a tightly forged *ko-itame* or *itame* with flowing grain and a tendency toward *masame*, particularly near the cutting edge; the *shinogi-ji* is characteristically wide and the *shinogi* stands high, features that strongly express the Yamato character. Very fine *ji-nie* blankets the surface thickly, with fine *chikei* appearing throughout, and the steel is consistently described as *saeru* -- bright and clear. Along the *habuchi*, *hotsure* appears frequently, and *yubashiri* emerges "in dotted succession" in the upper portion of the blade. The *boshi* is straight, commonly finishing with vigorous *hakikake* and tending toward *yakitsume*. Within the broader Taima manner, Aritoshi is distinguished by a forging that is "comparatively tight with little *masame* tendency" relative to other Yamato attributions, and by *ha-nie* of particular brilliance.
The NBTHK reserves its strongest praise for the luminous quality of Aritoshi's *nie*: "the shining, beautiful *ha-nie* adheres well, and the *nioiguchi* is bright and clear." This interplay of thick *nie*, vigorous *nijuba*, and *kinsuji* within a fundamentally restrained *suguha* produces blades that the examiners characterize as possessing "a deeply flavored and engaging style" beneath an overall "subdued (*jimi*) impression." His work embodies the Yamato aesthetic at its most refined -- dignified, contemplative, and rich in internal activity -- while the distinctive *nijuba* serves as the primary attribution criterion that sets his oeuvre apart within the Taima lineage. The NBTHK consistently affirms that among unsigned Yamato blades displaying these combined features, "judging it to be Aritoshi is the most appropriate conclusion."
Mitsusuke (光夫) — Mainline · 1375-1379. Tokujū. Smith of the Yamato Taima School.
Nobunaga (信長) — Mainline · 1394-1428. Jūyō. Nobunaga is transmitted as a smith of the Taima group of Yamato Province who, in the early Muromachi period, relocated to Asako in Echizen. Smiths using the same name continued for several generations, and these are collectively referred to as "Asako Taima." Their workmanship resembles that of the Kaga Fujishima group, and their period of activity is said to have centered around the Oei era (1394-1428), with the line continuing into the late Muromachi period.
In terms of forging, Nobunaga's works display *itame-hada* mixed with *mokume* and *nagare-hada*, with the grain standing out and showing a somewhat darkened tone characteristic of Hokuriku workmanship alongside a Yamato temperament. The *hamon* most commonly takes the form of an angular *gunome-midare* -- the hallmark of this smith -- though works in *suguha* and *notare* are also encountered. *Ashi* and *yo* enter, *nie* adheres well, and *sunagashi* and *kinsuji* appear. The *boshi* is often executed in *hakikake*. Among the more remarkable surviving pieces, a *katakiriba-zukuri* tanto displays two distinct modes of workmanship on its opposing faces: on the *sashi-omote* a *midare* based on *gunome* mixed with "boxed" elements, and on the reverse a shallow *notare*, demonstrating Nobunaga's capacity for vigorous, open-handed work rich in *hataraki* along the *habuchi*.
Signed works by Nobunaga are rare and highly valued as documentary material. Among his well-known works is one formerly owned by Hosokawa Sansai. His tachi, though typically found in *suriage* condition, clearly display the period character of the early Muromachi era and are of good quality. The range of his extant work -- from angular *gunome-midare* pieces exhibiting the full force of the Taima-Fujishima idiom to refined *suguha* tanto in *kenzen* condition -- attests to a smith of considerable versatility whose output carries high documentary value for understanding both the Asako Taima lineage and the broader dissemination of Yamato tradition into the Hokuriku region.
Tomokiyo (友清) — Mainline · 1319-1321. Jūyō. Tomokiyo was a swordsmith of the Taima school, one of the five major groups of the Yamato tradition, which flourished from the late Kamakura period through the Nanbokucho era with Kuniyuki as its founder. Reference works state that the first-generation Tomokiyo was a son of Kuniyuki, active around the Gen'o era, and that three generations bore the same name, spanning the Ryakuo and Oei eras. The smiths of Taima-dera were originally artisans attached to the temple, which helps explain why extant signed works are exceedingly few and the majority of attributions are made on unsigned tangs. A partially inscribed tachi reading "Yamato no kuni Taima Tomo" (with the remainder cut away), designated Juyo-Token at the 13th Session, serves as the principal reference piece for this smith. A separate Nio Tomokiyo, active around the Oei era, represents a related but distinct line descended from the Yamato tradition.
In the forge, Tomokiyo's work displays *itame-hada* mixed with *mokume*, partially flowing and tending toward *masame*; fine *ji-nie* lies thickly, with frequent *chikei*, and the steel is notably clear. The *hamon* is characteristically *suguha-cho* mixed with small *gunome*, with *ashi* and *yo*; *nie* attaches thickly, and along the edge appear *hotsure*, *nijuba*, *kuichigai-ba*, and *uchi-noke*, while *kinsuji* and *sunagashi* run frequently. The *nioiguchi* is bright and clear. In these features, the Taima school's distinctive traits in both *ji* and *ha* are strongly evident. The *boshi* typically enters in *midare-komi* with vigorous *hakikake*, sometimes becoming flame-like in character.
The broad construction with ample *hiraniku* and the Enbun-Joji-type silhouette culminating in an *o-kissaki* place Tomokiyo's work firmly within the Nanbokucho period. The internal activities within the hardened edge are frequently praised as outstanding, and pieces attributed to this smith characteristically show no slackness in the *jiba*, with exceptionally good states of preservation.

Toshinaga (俊長) — Mainline · 1352-1356. Jūyō. Smith of the Yamato Taima School.
Kuniyuki (國行) — Mainline · 1243-1247. Jūyō. Kuniyuki is regarded as the founder of the Taima group of Yamato Province and was active during the late Kamakura period. Among works of the Taima group, extant signed examples are few; only a small number survive with signatures by Kuniyuki and Aritoshi, while almost all others are works attributed as *mumei* appraisals. His two-character signature appears in two modes: one rendered in *kaisho* (formal block script) within the *kunigamae* enclosure, and another in *gyosho* (semi-cursive) form. Both varieties are considered extremely rare, and any *zaimei* tachi by this smith commands particular scholarly attention.
Kuniyuki's forging is a well-worked *itame-hada* mixed with *masame*, often showing areas of flowing grain and thick *ji-nie* with *chikei* appearing throughout. His *hamon* is typically *suguha*-based, gently *notare* and mixed with *choji* or small *gunome*, tending at times toward *ko-midare*. The *habuchi* characteristically shows *hotsure*, while within the tempered area *sunagashi* runs frequently, interspersed with *kinsuji*. The *nioiguchi* is bright and clear. His *boshi* tends toward *sugu*, turning *hakikake* or ending in *yakizume* — a disposition considered typical of Yamato workmanship. Activities such as *chikei* and *kinsuji* intermix freely, giving a lively effect to the steel.
Kuniyuki occupies a position of particular importance as the progenitor of the Taima lineage within the broader Yamato tradition. His work demonstrates the defining characteristics of Yamato-den forging — the prominent *masame* tendency, the bright and clear *ji* and *ha* described as *akaruku saeru*, and the restrained yet animated temper line — while displaying a refinement and individuality that distinguishes his hand from later Taima smiths. The rarity of signed examples only heightens the significance of each surviving blade, and his best works are noted for their *kenzen* condition and sound preservation.

Kuniyuki (國行) — Mainline · 1299-1302. Kuniyuki is regarded as the founding master of the Taima school, one of the five great traditions of Yamato Province, and his activity is placed in the late Kamakura period. While sword compendia list many smiths of this group, extant signed works are exceedingly few; only a small number survive bearing signatures by Kuniyuki and Aritoshi, and most examples are *mumei* pieces identified through appraisal. The school flourished from the late Kamakura period through the Nanbokucho era, producing blades that embody the essential character of the Yamato tradition.
The construction of Kuniyuki's surviving works displays the hallmarks of Yamato craftsmanship with pronounced clarity. Wide *shinogi-ji* and a high *shinogi-suji* plainly manifest the tradition's structural principles, while the *jihada* — *itame-hada* mixed with *mokume* or *masame* — is consistently well-forged from base to tip. The *hamon* is characteristically *suguha*-based, with *hotsure* appearing along the *habuchi*, *sunagashi* and *kinsuji* intermingling to produce lively activity, and the *boshi* tending toward *hakikake* ending in *yakizume* — features the NBTHK identifies as "Yamato's traditional method." In certain works, a somewhat rough *nie* is mixed into the temper, introducing what the NBTHK describes as "an element of Soshu temperament," a quality consistent with the older attributions by the Hon'ami family for blades of this group.
Despite the rarity of signed examples, the designated works confirm Kuniyuki as a smith of genuine accomplishment. A tachi retaining a two-character signature following *suriage* is praised as displaying his characteristic features "conspicuously" and is described as "an excellent work." The *ji* and *ha* across his corpus are noted for being "bright and clear," with *chikei* and *kinsuji* interweaving to give the steel a vibrant quality. These qualities affirm the Taima school's standing among the five Yamato traditions and Kuniyuki's role as its defining voice.
Tomonaga (友長) — Mainline · 1356-1361. Smith of the Yamato Taima School.
Tomoyuki (友行) — Mainline · 1247-1249. Tomoyuki was a swordsmith of the Taima group in Yamato Province, active during the Nanbokucho period. The Taima school, taking Kuniyuki as its founder, was a lineage affiliated with Taima-dera that flourished from the mid-Kamakura period through the Nanbokucho era. One tradition holds that Tomoyuki was Kuniyuki's grandson; among his works there exists an example bearing a Bunwa-era date inscription. Signed works by the Taima group are exceptionally rare, a scarcity attributed to their dependent relationship with the temple, and the great majority of surviving pieces are unsigned blades transmitted through *kiwame* attribution.
Tomoyuki's forging characteristically shows *itame-hada* with a flowing tendency toward *nagare* and mixed *masame*, a hallmark of the Yamato tradition; *ji-nie* adheres well, with *chikei* entering, and conspicuous *nie-utsuri* appears in the better examples. The *hamon* is fundamentally *suguha-cho* with shallow *notare*, mixed with *ko-choji*, *ko-gunome*, and *gunome*; within the temper, *hotsure*, *kuichigai-ba*, and *yubashiri* occur at the edge, and *kinsuji* and *sunagashi* flash repeatedly. The *boshi* consistently shows *hakikake*, often in a *yakizume* or *yakizume*-like manner. The NBTHK setsumei observe that, in comparison with Kuniyuki, Tomoyuki's works tend to display fewer conspicuous individual characteristics; yet the best examples present thick *ha-nie* with a bright, clear brilliance and vigorous internal activities of *ashi* and *yo* that place them among the finest achievements of the school.
The attribution to Tomoyuki is typically supported by the combination of wide *mihaba* and an extended or elongated *kissaki* together with Yamato-tradition forging characteristics. Most surviving pieces are greatly shortened katana in *shinogi-zukuri*, though a *kanmuri-otoshi* tanto displaying the school's characteristic pairing of *naginata-hi* with *soe-hi* also attests to the range of his work.
