One of the things I've noticed over the last few months since I've been using a DE razor is that there seems to be more hair in the sink. I'm not sure if this is due to increased proficiency or if it's just that there are less places for hair to get clogged than with a cartridge. Even on days when I just shave the sides of my face I notice more hair in the sink than I did before I started using a DE.
Just an observation.
