I have a fair collection (triple digits) of razors which span various blade styles (DE, SE, Injector, AC, Valet, Hair Shaper, Straight, and Lather Catcher Wedges) -- I've *mostly* stopped acquiring more razors, but I do enjoy the variety. Admittedly, when it's time to shave, I do stare at a bunch of razors for a while before the decision is made.
I use four razors pretty much exclusively. Well these four razor heads, the Fatip OC, Fatip SB, Fatip OC Slant, and the Fatip SB Slant. I have 34 Fatip models, which means many different handles. Does that count?
I have a drawer filled with at least 10 vintage Gillettes as well as some Fatips, Merkurs, and other modern razors, some of which are NIB. I used to rotate 4 or 6 razors but around 2013 I just finished a blade in a black handled Super Speed. Rather than changing both blade and razor I elected to change only the blade. I used that razor almost exclusively until November 2020, when I decided to let it soak and have a 'spa day.' In its stead I chose a red tip Super Speed, and 10 months later I'm still using it. The last time I opened the razor drawer was to drop in the freshly cleaned black handle razor. I have some terrific old razors, and some really nice newer ones, but I couldn't be arsed rotating them.
I have quite a few razors but lately I am enjoying using each individual razor for at least 10 or 12 shaves before switching to a different razor. This approach has allowed me to get better accustomed to each razor's unique attributes. Subsequently switching to the next razor in line has become more interesting since I am now better appreciating the differences between each razor. For example the last few razors I have used were my RR Lupo .95, RR Mamba .70, Schone OC and Gillette SS. Each of these razors is quite different but I really enjoyed using each of them and getting the best shave I can out of them.
I have a few favorites in my large collection of razors and to use them more, what I do is have them them in 5 different racks with 8 razors to a rack.
I have a Gillette rack, Schick injector rack SE, 2 ASR racks with Gem, Everready & star SE & 1 Rack with Modern SE & DE & proto type razors.( Just won a razor in a fund raiser forum rally its new adjustable razor, 4 only in the world made.)
I kind of make a rotation that out of each rack of at least 1 razor will be used and going by 52 weeks in a year my favorite gets 52 uses almost unless I'm using or testing a new razor.
36% are DE and 64% are SE and just truly enjoy the variety of different shaves from different razors and blade systems.
I would use 1 Cartridge razor for years and then Gillette would come out with a new Cart razor model and use it for many years ........... I was a Gillette fanboy for over 30years of cartridge razors. I still like using my Gillette DE razors to this day. A.S.R.Corporation razors are very good and use them a lot nowadays it seems and single edge(SE) shaving has advantages and at times in history was more advanced then DE razors IMO.
But its a hobby and a pleasure to shave and enjoy it so a collection we all need Razors, Straights, Brushes, Soaps, Aftershaves my moto is you can never have enough of anything.
Its great when you can look and pick your shave of the day with everything in a mix that way it is what it is a shave of the day and that is priceless
I have have my collection of razors down to about 10 razors. Some DE razors, some SE of the artist club type and a couple of GEM type razors. My favorite since I got it is the DE ATT Windsor Pro SB90 in aluminum. I really love that razor.
The one I use the most after that is the General SE with the Artist Club type blades. Those 2 razors are my favorites by far.
