Now we have to learn what "osameto" is. Osame is an order form of a verb, osameru.
That means "to put things back to where it comes from" in this case because we put our sword back to the saya (scabbard).
So when you hear "Osame-To", you put your shinai back to the taito position.
When you hear this command, you
1. sit in sonkyo
2. put your sword back to the taito position
3. stand up
4. quietly lower the left hand (the sageto position)
When you put your sword back to the taito position while you are siting in the sonkyo position, place the right hand on the upper thigh (close to your body).
When you do so, relax your right elbow and close the right arm pit. This prevents your right elbow from sticking out too much.
Osame-to is used all the time in kendo, of course, so please learn the correct way.
When we put our shinai/bokuto back to our invisible saya, we have to lift shinai up and place it in the taito position.
When you hear a command, "Sagetoh!", you put your sword back to the sageto position without sitting in sonkyo. The sequence is
Fairly easy, isn't it?
The most difficult words is to "hear the commands", I think. So learn how your instructors pronounce the commands so that you will not misunderstand.
