No Injectors, No SEs, no Str8s, no DEs... What would you use? My top pick, by a long shot, is the Personna Sensitive 1-Blade Disposable. 10 for a buck at dollar stores, and they're genuinely good razors - blow BICs out of the water. Second choice for me would be Personna's Twin IIs loaded in a nice Trac II razor ; but like I said, the Personna 1-blade throwaway is dynamite, not to mention convenient. My heavy-bearded uncle uses each for about a month before discarding.
You make a couple incorrect assumptions. First one is that if vintage razors were not available then a guy would continue to shave with the modern day junk that is on the maket. Merkur stuff not included. The second is you rule out SE razors and what are some of the disposables and cartridge razors but SE razors. Take the Bic disposables for example. Been there and done that with the "modern" razors and you can ask your question or even make a poll but it is ridiculous to ask it because vintage razors have not gone away and most likely will not in my lifetime. My answer to your question is to quit shaving and re-grow my beard.
I wouldn't call it a favourite,but the Trac 2 is a decent shaver minus a lube strip. Great for a quick shave when you have delerium tremens.
+1 Funny thing is that the trac-II is vintage, as in not widely available. I can find DE razors and blades just as easily as trac-II products. Sensor handles are headed that way too. I resort to the personna brand three blade cartridge when I absolutely have to, but that situation hasn't come up in two and a half years. There's always a way to make the DE or SE work.
Probably the Sensor, or any of its modern incarnations sold around the world like the Gillette Blue/Azul.
Nobody...I mean nobody...is going to say the M3? alright, I will. I like it better than disposables... although the 2 blade Personna's are pretty decent from the Dollar Tree.
I have heard before that you have leather skin. It must be true!! Looks wayyyyy better than using a cartridge!!!
I'd use the same thing I currently use 4 out of every five shaves, my Trac II. And besides, the Trac II is creeping up on its 40th anniversary... how much longer does it have to be around before it achieves "vintage" status?
