Katsuya just pointed out to me that in this week’s post whereas I described the gripping action as “the little and ring fingers making the strongest contact. The hands should be turned in with a feeling of chakin shibori”. What Matsumoto sensei actually said was “Hold the shinai with a feeling of chakin-shibori by the Hypothenar Eminence ( Sho-shi-kyu) of each hand.”
To be honest, I have never heard of the Hypothenar Eminence, but according to Wikipedia the “hypothenar muscles are a group of three muscles of the palm that control the motion of the little finger”. With this in mind the post’s description of the grip is pretty much in line with sensei’s directions although the translation diverges from the original.
*The arrow indicates the Hypothenar Eminence.
