According to the interweb.
"Cabiri Königin Solingen" refers to a specific brand and product from the German "City of Blades"
- Cabiri was a trademark used by Johann Emil Kronenberg (also known as Cabiri-Stahlwarenfabrik GmbH).
- The phrase "Königin der Klingen" (German for "Queen of Blades") was their advertising slogan.
- Solingen is the German city famous for centuries as a center of high-quality blade manufacturing, a reputation it maintains today with companies like Wüsthof and Böker.
Cabiri products included razor blades and likely other steel ware, such as manicure items. The company registered its brand name in 1923 and was active in the early to mid-20th century. You can often find vintage Cabiri items, such as straight razors or blade boxes, for sale on collector websites
However - I cannot find a photo of any DE from them.....
