I've found nothing that beats vintage Gillette double edge razors.I have two from my birth year,1961,another made in England,these are undated,but all function flawlessly.Add a 100 pack of Feather Hi-Stainless blades,bout $25 on Amazon and last me a year and a half,some Taylor of Old Bond Street Sandalwood Shaving Cream,a brush and a mug........I'm convinced no better shave exist.
Here's a nice one ........gotta be close to your birth year.This'll probably go for $25 or less.I think the most I've ever paid was $35.

The Fat Boy's are nice but my favorites are the Super Speeds like the one linked above.
