Thread: Numbers on Gillette razor blade?

So, I got my first DE shave in today and I feel pretty good. But as I loaded the Gillette 7 O'Clock razor into my Gillette Super Speed I noticed it had numbers on both sides of the razor blade. I took a guess and surmised that maybe it means to shave twice on each side. Four uses maybe.

Does anyone know what the significance of the numbers means? Please shed some light on this for me. Perplexed.

I copied this from a google search:

The majority opinion is in favour of them being some sort of manufacturing mark - if you imagine the blades being made there would be 4 edges to be honed/ground/sharpened - if they print on which edge is which they can ensure (in theory) that when one of the hones/grindstones/sharpeners starts to wear out that they can replace the right one first time...

Gentemen:

To my knowledge, those are production markings and bear no other significance that I know of.

Thanks. We'll see if anyone sheds further light on this then I'll call it a dead issue.

It's one of those mysteries of life. You see, one day a production supervisor at Gillette says lets rive em nuts. We'll put numbers on the blade and they'll go crazy trying to figure out what they mean.

Only a newbie would be asking these questions. Go figure? Don't worry, I can assure there will be many more.
