Kumitachi #1

Uke-Dachi raises to jodan gamae to strike which creates an opening. Uchi-Dachi quickly enters with tsuki to the throat but Uke-Dachi quickly counters with a cut to the wrist (crossing the right foot over the left in doing so). Uchi-Dachi then leans-in and cuts with kirikaeshi left (blocked) then kirikaeshi right (blocked). Uke-Dachi takes large backward steps during the blocking but rotates his body sideways during each block.

Kumitachi #2

Both Uke-Dachi and Uchi-Dachi raise to jodan gamae. Uchi-Dachi attacks with gedan gaeshi to the knee (Uke-Dachi blocks moving backwards, not to the side, and quickly cuts to the wrist). Uchi-Dachi pivots the hips to block the wrist cut and counters with tsuki (with step) followed by kirikaeshi right (Uke-Dachi blocks/pushes moving backwards). Uchi-Dachi repeats the tsuki (with step) followed by another kirikaeshi right.

Kumitachi #3

Both Uke Dachi and Uchi Dachi raise to jodan and strike. Upon blade contact Uke-Dachi pushes to the left to create an opening. Uchi-Dachi blends and counters with kirikaeshi (left) then kirikaeshi (right). Uke-Dachi blocks with large steps backwards.

Kumitachi #4

Both Uke-Dachi and Uchi-Dachi withdraw bokkens to their side, then approach each other with a thrust tsuki (no step). Uke Dachi is in fact moving backwards but his tsuki thrust is in a forward motion. Uke-Dachi pushes to the left and Uchi-Dachi counters with tsuki (blocked by Uke-Dachi stepping back and the bokken raised to shoulder height during the block. The  raised block avoids giving an easy opening to Uchi Dachi), then kirikaeshi (right). Uke-Dachi blocks with large steps backwards.

Kumitachi #5

Uke-Dachi lowers to offer an opening. Uchi-Dachi raises to attack with menuchi but is forced to step back and block right as Uke-Dachi quickly enters with left kirikaeshi. After blocking, Uchi-Dachi counters with tsuki (which Uke-Dachi blocks stepping back). Both move forward in a kaiten movement and left kirikaeshi cut to the do (waist) that becomes a mutual block. Uchi-Dachi then raises and attacks with jodan menuchi, which is blocked by Uke-Dachi stepping back.
