Hello everyone. I'm practicing Aikido (Steven Seagal's style) for many years. Also i'm a knife defence and aikido instructor in police in California. So i wanna show you couple videos to show that Aikido is a great and powerful self - defence martial art.
1) First video is fast hand movements - http://youtu.be/tlCGf_AhVl8
it's looks like win chun, but it's my variant punching in Aikido!
2) Second is Aikido against real knife - http://youtu.be/MxfHfaWoWgc
