I have a FatBoy handed down to me by my dad 46 years ago. Almost never use it & never really liked it. Gillette abandoned the design very quickly as consumers in that era preferred the slim after it was introduced. I seem to be the exception though as I rarely read anything but very high praise for it and it seems to have reached holy grail status among most traditional shavers. I keep mine since it was my first razor and given to me by my now 97 year old dad. It will eventually go to my son who has a greater appreciation for vintage razors than I do. That said, in the vintage arena he vastly prefers his New Long Comb and his New Improved to any of the TTO adjustables.
