Well, more specifically of kote. In Saito's "Traditional Aikido", the kanji for kote are: 小手 which is literally "small hand". What is the meaning and origin of this spelling?
In Chinese, xiao
小 "small" is said to derive from the associative compound of the middle line dividing something into two smaller parts. Kote
is the line at which the hand is divided from the forearm.
