It's all about the stroke and the touch guys. Keeping the elbow up helps with keeping the blade flat. The stroke is developed. You really want to develop the feel and touch. I have always found that by using the second hand, it is harder to find that right feeling. This might be easier for me to say considering the thousands of razors I have honed.

Considering the above, if it's two hands that works for you consistently, then that would be what you should use. I would not recommend this for newer guys who are already having so much trouble with so many things. Less is better. Simple is easier.......

Now define simple.........

Have fun.
