So, I'm the type of person who enjoys little surprises. I'm wondering if I'm the only one who will get a bunch of different types of blades "sample packs" and then mix them all up and put them in a pile. The next day, I just grab whatever blade is on top and shave with that. Eventually I'll settle on one or two blades, but for now when I'm trying a whole bunch, I like the surprise every day of a new blade.
