"The Ten Students"
CHOGI KO-EI (f: MITSUNAGA, grf: SANENAGA): His father will be in
        the style of SANENAGA. Originally NAGAYOSHI, his skill 
        and resulting fame earned him the reverential, Chinese 
        pronunciation of CHOGI. Born: SHO-O 1288, and died in 
        KEN-TOKU 1370. TOZAEMON. One theory has this one long 
        career, with a marked decline centered about KO-RYAKU 
        1379. Most writing places SHO-HEI 1346 to EN-BUN 1356 
        periods for expected pieces. DAITO are rare, TANTO 
        plentiful. NAMBOKUCHO wide TACHI with O-KISSAKI and 
        NAGAMAKI. TANTO are wide and comparatively small. 
-Early: NIOI HAMON. MOKUME HADA under standing UTSURI. 
-Later: NIE-DEKI with JI-NIE and CHIKEI tracing grain.
        GUNOME-MIDARE swings on wide undulations of the YAKIBA.
        TEI-JI 1362 period finds NOTARE HAKO-BA resembling SENGO
        MURAMASA School (Note: Unlike CHOGI, SENGO will show 
        MASAME HADA). TOGARI pulls on O-CHOJI MIDARE BA and 
        SAKA-ASHI may be seen in KO-GUNOME MIDARE HA. Skill level
        declines in swords of KO-RYAKU 1379 and are supposed the
        work of CHOGI(2). The CHOGI MEI is wide and appears 
        stretched sideways, as if a roller had squeezed or 
        smeared normal characters across the tang to the right. 
        BOSHI: MIDARE. KO-MARU at the head. See BUNKAZAI CHOGI

Figures are a lively and dynamic mix of smooth GUNOME and
KO-GUNOME mounds with compressed KO-CHOJI KO-GUNOME
defined of KO-ASHI that tug in different directions.
YO and NIE JI-BA dot occasionally while smoke NIOI makes
as many efforts at TOGARI. The CHU-width KO-NIE and deep
NIOI YAKIBA widens somewhat in the mid where GUNOME groups
into peaks that push and lean. SUNAGASHI and KINSUJI
corrupt at opportunistic sights.
MIDARE-KOMI BOSHI takes a wide arc to the FUKURA and
before walking to a slightly HAKIKAKE KO-MARU head.
SURIAGE NAKAGO has four MEKUGI-ANA and a KURI-JIRI that

KANENAGA(1) TEI-JI (f: KANESHIGE): To KA-KEI 1387. Also thought
        possibly the son of NAGASHIGE. 
   There are two theories: 
        First - KANENAGA was one man working until the O-EI. 
       Second - There were two generations, the 2nd, a CHOGI student
                who presents work in SHI-TOKU 1384 to the O-EI.

           Early is NAMBOKUCHO, possibly SAKIZORI TANTO. Wide 
           bodied, thin blades. Later we see elongated SUN-NOBI 
           MU-SORI of OEI fame. Early work is seen to portray the 
           SODEN style, with TOBI-YAKI HAMON patterns appearing 
           almost HITATSURA. KO-NIE DEKI KUZURE-like GUNOME and 
           O-CHOJI MIDARE BA, SOSHU style. Most long swords are 
           O-SURIAGE. Note: Some ZAI-MEI may not fit the mold. 
           KANENAGA: Small MEI in thick strokes.
