I have been told that blades stamped Zwillingswerk came out of the factory totally finished, others did not. I don't know if they were ground or scaled or what elsewhere, but they did not leave as complete razors.
We need Inspector Clouseau. Maybe it's just a simple name change to extend their market. As English is the international language of trade and commerce; except in Texas and California. On Lynn Abram's DVD he mentions that a prewar Henckels is preferable; well then there must be a way to date these. I have an NOS in box Henckels Twinworks Friodur purchased from Bob's Razor Works and it has the number 451 stamped on the tang. The NOS Zwillingswerk is not number, and it's spine is straight and bevel lightly honed. Somebody must know the story on these vintage/antique NOS Friodurs, as they are very desirable.
Here's what I've learned so far - Zwillingswerk razors are significant since 1. they were completely finished in Henckels factory
2. the German sounds manly
I'll try to search the web for more info.

If it says "made in West Germany" ... it's not pre-war.
Well that means that all razors made after the Berlin wall are stamped Zwilling, maybe.
No, it doesn't. It's already stated a few times in this thread that the Zwillingswerk stamp is on razors that were totally finished at the Henckels factory, with the exception of at least some of the NOS Friodurs that are popping up.
