According to Ed Fowler in his book, Knife Talk, The Art and Science of Knifemaking, the Richtig legend is TRUE.
Ed states in the book that he was able to test some Richtig knives owned by a collector named Harlan Suedmeier. After rigorous tests, including a 90 degree bend test, he concluded that Mr. Richtigs knives were, "A cut above the rest". See the book for the complete details.
And now for your drooling pleasure I humbly submit:
