I'm at 20+ and that's nothing really, some people have 20 of one type of razor. I have 8 Sheffields, my fav.
I have been really thinking about this lately, esp about what Robin said. I really think 7 is the number I want, 7 quality blades one for each day, and I'm making an effort to do just that.
My problem is worrying if the people I sell to will keep the blade in good shape or let it go to waste, it is after-all an antique, it would be nice to know the blade will be well taken care of.
