German made blades

Yesterday I went by the local antique shop looking for shaving gear. Mostly I was looking for razors, mugs and brushes. I saw three brushes and one rusty SR. When I asked the owner if he had anything else, he showed me a box of DE blades, approximately 50 all one brand. I don't remember the name, but I saw they were made in Solingen, Germany. I do remember that they were in blue and white box. Do any of you know what brands of blades came from Germany?

Not interested in buying them, it's just driving me crazy I can't remember the name.

Thanks
