Dad Jokes

((Kama were basically used as small, single handed scythes for rice farming, bo just literally means 'staff' and the original use of sais, as I was told by my Karate Shihon, was that they were basically used , one in each hand, to easily pierce a baled up bundle of crops and then toss them into a cart... though as with a lot of Okinawan Karate history, that may be apocryphal, none of that is well documented ... because Karate isn't actually Japanese in origin, it is Okinawan, it was the self defense style invented by Okinawans resisting Japanese imperialism with just their farming implements, and a lot of their recorded history got destroyed))

((the sai pun is supposed to be that it sounds like sigh))
