Or develop a unique battery and market that, too.
How about if you dip your razor in hot water for 10 seconds. That might work. But it wouldn't make money for Gillette, so it must be a bad idea. Sorry I brought it up.
But didn't you read this quote from the patent application?
If you are using something that doesn't work, try something else. Have you tried DE yet? I was using a Mach 3 and was getting horrible razor burn on my neck. I switch to DE and the razor burn went away and I never looked back. So much happier using vintage DE razors.I have a Mach 3 that vibrates. Supposed to help with razor rash...doesn't work. It is what I am currently using.
