The fine points of KOTETSU can not be covered in the
short. His ¨works show the sophisticated reserve that
defined SHINTO.
Blades ¨are KO-MOKU with MASAME in the SHINOGI.
JI-NIE. Moisture. CHU-¨SUGU NOTARE,
KO-NOTARE GUNOME-MIDARE of fine NIE. The
JI-HADA becomes strong, or rough, toward the MACHI
area. Clear, strong ¨steel.

The Honami correctly stated that 
        Kaneshige was the teacher of Kotetsu

There has been notion circulated that Kaneshige was
younger than his student, KOTETSU and that therefore,
the KOTETSU's teacher must have been Kazusa-no-Kami Kaneshige's father, IZUMI-no-KAMI.
However, everyone was younger than Kotetsu. Kotetsu
was an armor-maker until he took up sword-making at 50. Joining the competition of comparatively youthful smiths
in the Capitol, he was known as the old-man with the
old-tricks (of using old iron) and hence his name:
Ko-Tetesu "Old-Iron"
He did learn his craft, as stated by the Honami, from the
younger man, KAZUSA-no-KAMI KANESHIGE
