I train in Aikido and the basic sword form was included with the typical grappling techniques. I don't own any, I bought a wooden bokken so that I didn't beat up the Dojo's stock. I guess one thing I liked was that it was challenging, a lot harder than I thought it would be. It does help your form, you really notice your bad habits when holding a weapon. As for using one in real life, not unless I had it in my hand when I am attacked(which I hope is never
). I'd rather throw the chair that I'm sitting on rather than trust my sword skills against an armed attacker, but that's just me.
