The Filoso is an interesting blade (I read the reviews after). Probably very variable, but from my one shave, not great, not even "good," but certainly acceptable, at least for me. Also not sharp (very), but it's a DE blade that worked, so maybe the press is (somewhat) undeserved. No idea of the cost, but if it's really cheap, a not totally unacceptable weekend blade. And all my blades are one-and-done, even the Feathers. Won't be buying a tuck, and probably no second trial, but no worse than the range of Voskhods I've used, or a really bad run of Derbys. My go-to is generally Personna, but Feathers in tried and true razors that I'm confident with. It's all good in the often experimental world of DE shaving, and I suspect the design of the M3teorite contributed largely to the non-destructive shave with the dreaded Filoso!
