Don't forget you are practising/learning about AIKIDO. Your choice of weapon is of no importance. Your most important weapon in aikido is your own mind and body!
Train your mind and your physics will follow.
Even the most strong material will break if used without the proper "state of mind"
Even the most weak techniques and/or materials will last and perform for you if you use the right "state of mind"
What is the proper "state of mind" you may ask yourself?
The truth is in dicovering your inner strength, your KI!
Train, improve yourselve and train more.
You will see the light when you progress in your training....
and you will find out why a "weapon" like the bokken is only meant for excercise purposes only and that your primary choice of weapon is your own spirit!
