Deja Vu... Similar thread lost in the great server crash of 2012

I found that the cheap, $10 for 12-16 single use razors last much longer for me than the $20 for 4 replacements heads. The guy that started the original thread was saying you can take the disposable razors and run them backwards on your skin (similar to what you do with the straight razors), and that helps keep them sharp. All I can say for sure, is that I've been on the same $10 pack of 12-16 razors for the past 6mo easy. In fact, I think i'm only on my 3rd or 4th razor now. They're still super sharp and make shaving a real treat now!
