I've used a two handed stroke on my Norton 4/8K combo and got acceptable results but I recently got a DMT D8EE and couldn't get it right ... till I tried only using one hand and in the space of 2 laps the razor went from not passing a HHT to scaring the hair in half.

I think that I was able to use a lighter stroke by only using one hand and where the DMT cuts fast that light stroke was needed where as on the Norton there is a little more "give" since it doesn't cut as fast.
