Interesting reading!
While I don't track in quite such detail, not in a spreadsheet for easy lookup say, a quick skim down my list shows I'm not actually a 1912 man at all!
I started the year with a run through my Star, Treet & Pal/Personna razors, clones of the Gillette Tech. I proceeded through February going into my Gillette Techs; quick smattering of 1914, 1924 and ... a 1912 ... then onto the Gillette Guard for over a month! Gillette Trac II then back to the Star, Treet & Pal/Personna DEs; GEM Junior, back to the Gillette Guard ... and it's not until October that I have a run of 1912 shaves, which brings me up to December where I've shaved twice, both with a Vincent disposable straight.
Blades? Well, I ran through the first half of the year on various Rapira before switching the the Gillette Guard (no blade choice there), onto the Feather FII on my Trac II; smattering of Sputnik, Rhino & Treet Carbon on the DE front and the mighty GEM Stainless PTFE for my single edge shaves. Disposable straight shaves have been with those Feather-Cut blades you see for brow shaping - they shave faces perfectly well and feel a tad like a frameback in use, certainly compared to the long Personna shaper blades.
Soap has been a mixed bag, but I'm seeing MWF & Wickham's 1912 regularly. Maybe I am a 1912 man, afterall. I'm also seeing Rose of Bulgaria cream time after time and Arko seems to stand out with surprising frequency. Aftershave, it's been the classics: Brut, Old Spice, Tabac, Jovan, Clubman & Pashana. Brushes? All sorts! All over the place there, but boars and synthetics.
As this year draws to a close, I'll join
@riverrun in wishing all here a happy new year to come.
