Kiriotoshi sequence

This sequence was shot at the Kenshikan, Melbourne. Takizawa sensei is demonstrating kiriotoshi waza against Shinoda sensei (renshi 6 dan) while Yano sensei (Kenshikan head instructor) watches on.

As you can see by the action of the hands they are both cutting downwards. The third frame above shows the point at which Shinoda sensei's shinai stops. The kiriotoshi movement, although it is travelling in the same direction as Shinoda sensei's attack, has managed to halt his attack so effectively that there is a small bend in the shinai. This seems to go against the laws of physics! I am confident that Shinoda sensei was not 'pulling' the cut, that he was genuinely going for Takizawa's men. Video below for moving reference.

This is a sequence that needs a genuine slow motion camera to record it...
