I get a BBS and blood-free shave from my Edwin Jagger DE87. From time to time, though, I get the urge to use my father's old Gillette Fatboy...which is in excellent condition for being 40 years old. Unfortunately, my Fatboy cannot replicate the quality of my shave with the DE87--even with a mild setting of 3. My Fatboy gives me a DFS at best, along with a few weepers. I certainly don't think the Fatboy on 3 has a greater blade exposure than on DE87, so am I dealing with a difference in blade angle between the two razors? Just trying to figure out why I'm having such a difference in shave quality.
