No probs sire.
Hmm......I guess one handed slash is less effective than the double handed one cuz it only uses one hand so the power is less whereas say if you miss the attack one handed slash gives you the option to defend against the enemy's attack with his free hand which is not possible with a double handed sword slash @_@
*takes the bokuto*
After listening to your instructions,
I hold the bokuto in my right hand like a sword. I walk towards the dummy slightly tilted showing off my left side. As I reach about a meter away from the dummy, I swing my arm slashing the dummy's chest from the (my) upper right side to the lower left side and I regain my composure looking straight at the dummy.
