Re: Center of effort?

Lars Parrington
Having read through this series of articles and your previous article devoted to "Center of effort", I can't understand what you mean by the term. It seems like it could be the angle off horizontal of the line formed between the users rear hand and the tip of the blade. But, if so, I fail to see how there could be a difference in value between for example a BU and BD smoother if both are cast iron and have the same handle and similar handle position. I do understand that those two planes would have different centers of gravity.
