Thought: Suriage Waza

I looked up the term Suriage (also Suri-ageru):

"suri-ageru (v.)

To deflect the striking opponent's shinai with one's own shinai, swinging it upward from below and contacting the opponent's shinai as if drawing an arc with the tip of the shinai (ken-sen), thus making the opponent's strike invalid.  There are two ways of doing this: one way uses the left side of one's shinai, and the other way uses the right side.  It is important to snap one's wrist when moving the shinai and to not leave a gap between the deflecting action and striking action."
