Hi
Hi, also written as 'bi' are the grooves on
a Japanese sword, usually located in the Ji,
the area just above the shinogi,
or ridge line. There are many styles, many of them
are presented below. |

|
Bo-bi
A wide long groove down the length of the
sword. Its located above the Shinogi and below the
Mune. This groove is not the shinogi line. The end of the groove in the
Kissaki can vary and details can be located in
the references.

|

|
Shinogi-bi
This grove is similar to the Bo-bi except
the lower part of the groove is the shinogi line.

|

|
Futasuji
Two long grooves along the blade. If the
grooves are short then its called Gomabashi as
seen below.

|

|
Soe-bi
If a blade has Bo-bi and another small
thin groove below the shinogi its called Soe-bi.

|

|
Misuji-bi
There are three long thin grooves, also
called Sanbon-bi

|

|
Gomabashi
Two short thin grooves that start near the
Machi (near the Habaki) and do not go the length of the blade. If the
grooves are along the entire blade they are called
Futasuji-bi (see above).

|

|
Koshi-bi
A short single groove that starts near the
Machi and does not go the length of the blade. This is like Gomabashi but a
single groove.

|

|
Kaku-dome
The groove stops in front of the Machi and
has a squared end.

|

|
Maru-dome
The groove ends in front of the Machi with
a rounded end.

|

|
Naginata-bi
This style is seen most often on Naginata.
It has a Bo-bi from the Machi part way down the Ji, then there is a small
groove, called Soe-bi, below the Shinogi and past the end of the Bo-bi.
