I got to thinking today as I shaved with a SR and thought about the thread on the newest Gillette razor, that I have spent an amazing amount of money and time trying the latest and greatest "new thing" during my 50+ year shaving history, and wondered how many others have tried that I haven't. Here are mine beginning with my first and working forward:
  1. DE Gillette (s)
  2. Schick and then Wilkinson Sword injectors
  3. Remington Electric
  4. Gillette cartridge (one/two/three blade over the years)
  5. Straight
  6. Norelco Triple Head electric (Had original and floating at different times)
  7. Gillette Fusion
  8. DE Muhle (and others)
  9. Straight again

So I count that as 6 or 7 varieties, even though there were subsets. What about you? Did you hit any I haven't?
