The original classical pronunciation is Chiburui (see note). Nowadays some people especially the younger generation say Chiburi. Both are acceptable in Iaido. However Oe Sensei always used the term Chiburui For this reason I shall use this pronunciation. Chiburui is the action which shakes the blood off the blade before putting it back in the Saya. In Seiza forms Chiburui movements are remarkably large and industrious.
