Numbers on Astra blades

[Thumrait]

I've never used a safety razor before and I just got my first one (a Gillette Slim Adjustable) and an assortment pack of blades. The first pack I grabbed was some Astra Superiors so I figured I'd start with them. There are numbers printed on the blades in the corners, a 1 and 2 on one side, and a 3 and 4 on the other side. Do they mean anything? And there are 4 circles on one side, they look like glue spots. Do they do something?

They mean absolutely nothing in regards to your shave-

BTW, Welcome to B&B!

Welcome!

The numbers mean nothing to the end user (as mentioned above). They are put there by the manufacturer as part of their quality control.

The 4 circles are wax/glue spots put there by the manufacturer to prevent the blade from shifting in its paper wrapping. It appears to be a way to prevent the blade from dulling during wrapping/packing/transportation (the edge can't rub against the paper).
