Thanks Danny

Just one thing I would like to add that I think I should of mentioned also. Is when preforming a karate chop - when the hand is turned towards the plane - the motion the hand is going to accelerate is parallel to the plane line.

In this context you could say you are preforming a karate chop along the plane line - it is not right to say it in the context of along in the sence of directly pointing towards the plane line....ie frisbee toss.
