Thread: Bern Extra Razor with ultrathin ground, has anyone Infos?

I got this Razor a few Days ago from a lot, bought in the UK but now i have the Problem, i dont know nothing about it
The Razor ist 13/16" wide (maybe it was 7/8"), full hollow with belly grind and incredible thin grounded, i only saw one similar thin razor as long as i collect Razors before, a very thin Beter Modello XXXX based on a No.14 Blanket.
The Nail Test shows an aluminium-foil like thin Blade producing a bulp up to wall with nearly no pressure but its own weight.
As you can imagine, the sound is very loud and im sure (didnt shaved with it until today) that it will be a very gentle Shaver.

Has anyone sawn this Razor before or has additional infos about it?
