I attended a "Freestyle" class over the last week and it had me thinking. The Sensei was confused as to why I didn't have "Self-Defence" techniques in my syllabus and to why I used the Kata as my Core and Ethos into Self-Defence and that they weren't just "dances" etc.
I've never been grabbed by my wrist in all my living days by anyone other that my Parents/Grandparents or teachers and Police officers etc.
I wonder why other styles teach wrist grabs?
Why do they do it and has anyone else ever been grabbed by the wrist by a bully, or not nice person or mugger in their life experience?
The Only thing I can point it towards in Martial Arts ethos is from the samurai and someone grabing the wrists to prevent the samurai drawing his sword etc.
