Just had this 7 day set land today. Very minor rust on the tangs, otherwise in great shape. They all have yet to ever be honed.
KOBAR was a brand belonging to Friedrich Emde (as was the trademark Kiebitz). The company changed name to Gebrüder Emde and later EMDE. They produced razors between 1902 and 1939.
Dang, those are super cool. Neat that you’re the first to get a shot at honing them.
I’m pretty fond of that part myself!
