Let me start off by saying'I hate you all!'. Since my last shave, on Friday morning, I have acquired 9 new razors. The black beauty I inquired about Friday morning and then these this morning after looking on Craigslist last night: The 2 on the sides are plastic handled schick slants, from top to bottom: Schick..don't know 1968 (1) Gillette Knack 1965 (4) Fatboy 1961 (3) Fatboy GEM Micromatic slant (Pats. 1739280 and 1773614) Gillette open comb ball end with no markings. What is the last Gillette and who do you recommend for refinishing? Thanks for the new addiction!!!
