I have a Henckels Friodur with the number 89 1/2 on the shank. I'm looking at another one on the bay with the number 70 1/2 on it. Both razors have 9/16 wide blades and from the measurements given it seems a dead ringer to mine. There has got to be some difference. Why otherwise would the numbers be different? Anyone have information on Friodur numbers?
