So I am fairly new to the DE world. I have a sample pack of blades (Gillette green, Bic, bluebird, and Feather). My technique is obviouse getting better, and I am starting to feel the difference betweent the blades. I have not tried the feather yet until I get a little better. However, I do notice the bluebirds are my favorite, but I am not convience it is the blade but possible my technique is better. So my question is how does one try to compare one blade to another? I have a thought that if I keep all things equal (brush, soap, razor, and the same day) I would shave 1/2 the face with one blade and the other 1/2 with another blade. Has anyone try this crazy test? Or I am just to obsesed to find the perfect blade. Any thought are appriciated (except the "don't worry about it" because that wouldn't be in fun).
