The Key I think is,I learned that Hoarding Razors is not a good thing,you end up with perhaps 100s of razors that never get used (I did that)
I fixated on one rare brand,sold off all the rest and concentrated on collecting the best of the best.
I have 10 Razors Now,they all get used,they never wear out,so need to ever buy any more (well I did Buy a Palmera last month for real cheap:)
If I can get them for under $35 am still in the game, but no more collecting for me.
