Video of rotational short stick strike to wrist
The Omote kuri kote hanbo (ימכת חיצונית בסיבוב לפרק כף יד יריב, אומוטה קורי קוטה, מקל קצר, נינג'יטסו) is a short stick (Hanbo) technique in Ninjutsu. The heavy weight of the traditional material of the Japanese short stick - Oak - makes one hand swings problematic because of the inertia of the stick.
