I survived a lathey foreman
I don't think I would buy that many blades of one brand, 1 bought 3 Schicks(7 per Pack) & 1 personna (20 per pack) injector loaders and that was 3 +years ago and I still have a lot of blades left in the loaders. I use other razor brands also like Gem and Gillette so it will take a little while longer to get through them. I will agree with you on the Personna blades being a little sharper and not as smooth as the Schick blades & that is balancing act of you gain on one side but give up something on the other side.. I can buy 500 Personna blades for around 104$ with free shipping from Connaughtshaving.
The Personna's will last a little longer also IMO.
