Numbers on razor blades

Have converted over to DE razors and blades for about a month now. Tried 2 different types of blades so far (Derbys and Tesco own brand). So far, gotta say that I prefer the Derbys.

Anyway, came over to France to visit the in-laws, and went to the supermarket, and saw some Gillette Bleue Extra. So, I bought those to try out. Haven't gotten around to trying them just yet, but they sound like a lot of members find them ok. Should be blade changing in a couple of days, so will try one then... If any good, might bring a few packs back with me. At €1.72 a pack of 10, seem quite decently priced.

Anyway, one thing I have been wondering ... on both the Derby's and the Gillette's, there's markings and numbers on them (i.e. arrows and 1 & 2 on one side, 3 & 4 on the other), as shown in the picture:



Would appreciate any information on what these mean, and whether it's anything that I should be paying attention to? lol

All in all tho, finding the DE shaving to be quite a good change over. Still getting a bit of shaving rash, but tried less pressure, a couple of different creams etc. So, think it's my skin (as only happening in one area)

Great site by the way

B&B requests the blade manufactures to stamp blades different ways just to get folks to ask questions here about secret meanings of things JK (of course)

Actually, it's just part of the manufacturing QA ....or so I have been told. Hmmmm, maybe that's just to stop me from finding out the real truth behind it.

They exist to help in the manufacturing process and have no meaning at all to the end-user. Ignore them!

HERE is yesterday's incarnation of this daily question.

Oh no, not again!

Just when I said that I had not seen this question for a while - here it is again! My smart *** answer is that it is to keep track of the individuals who put glue spots on the blades or wrappers.
