The Japanese saw

The 'teeth' of the saw here are facing inward rather than outward as in the west. The Japanese feel that their greatest strength is in pulling towards their center. In the west our greatest perceived strength is pushing away using force. interesting to contemplate...
Think of the difference between boxing and martial arts. In martial arts it's known that when your opponent gets too far away from you is when you can get hurt. Once you bring them in towards yourself you have more control. SOMEONE TELL OUR GOVERNMENT THIS!!!!
And yes, I get that the Japanese also used bombs during war- I'm not saying they are saintly- yet the wise ones of their culture knew these things long ago. I'm not sure our culture has yet found wise ones... we are not old enough as a culture yet, as we are still in cultural toddlerhood.
