Hello, I found such blades at home, they are probably 30 years old already. What can anyone say about them?
I have them in my Perma-Sharp saloon blades as well. For some or the other barber Shavette that takes half blades.The envelope looks prettier than the modern version, does not dazzle in the eyes. There are holes on the blade itself, it is not clear for which device ... How they work, I will tell you tomorrow or the day after tomorrow.View attachment 1501267View attachment 1501268
