I think there is a clear distinction between tools and approaches used to resolve conflicts prior to it actual coming to blows...becoming a physical altercation...and those used once it has become physical. ...
To paraphrase what one of the more highly though of Aikido teachers here said years ago...."a knife is for cutting vegetables or for cutting people...you need the skills at both to make the right choice of when to use either....."
Yep. That's also I think what Basia was getting at in her posts.
