I've been trying to follow the common advice of stropping with no pressure - just the weight of the blade. But I'm finding that unless I apply a bit of pressure I can't get smooth, consistent contact on the strop. Am I overdoing the 'no pressure' idea? Is a little pressure needed to get good contact of blade to leather? I know it's hard for anyone to say without seeing me strop, but what are your impressions of how much pressure you apply to get good results?
