Dirt on the mat? That's what it's for!
I've never even heard of most of those razors and 100 M&F's? It's hard enough getting just one, let alone 100. So you have sold all the M&F's and now have mostly Simpsons Manchurians?
I have a thing for brushes too but my modest budget has limited it somewhat. Still, I have 26mm Shavemac's DO1 2 band & 3 band, Chubby 2, Paladin Lotus, & a M&F so still a nice collection.
Yes, after a brush with a psychologist I realised my M&F madness and decided to invest in my children's education instead...
