I picked this up for a very reasonable price at an antique market but have so far been unable to actually identify it. I don't usually buy a blade without at least 10 minutes of research on the smart phone, but there was another potential buyer lined up right behind so I did not have much time to think about it.

Its a 5/8" with a barbers notch and has the inscription of "Barbers Special - German Hollow Ground". The trade mark is E S B K in clockwise diamond pattern with a diamond around the E. I have no clue what the trademark stamp is on the reverse side.







Maybe my google-fu is rather weak, but any help would be most appreciated.
