Sorry if this sounds ignorant, I'm pretty new to straight razor shaving. im just curious why people have like 10+ brushes and rotate them everyday and such. I can see if you are a collector and brushes are your thing then that's one thing but theres a lot of people with a whole variety of brushes. I have a badger hair brush and it works great. I can't see a reason I'd go start buying a bunch more and use a different one every time I shave. As my first brush just getting into it I bought a cheap like 30$ brush so I can see in a while upgrading to something of higher value and quality, but I probably wont use more than one brush.
