It's a safe assumption that this knife was made in the 1950's or 60's
In the late 1970's early 80's those odd clip pointed knives from Japan were made using her name, but this isn't one of those
She was most famous for being the person who brought omelets to the United States
Now the only thing people remember of her is this book:
Dione Lucas (10 October 1909 – 18 December 1971) (pronounced DEE-OH-NEE) was an English chef, and the first female graduate of Le Cordon Bleu.
Life
Lucas was fundamental in establishing an extension of the famous Paris culinary school in London in the 1930s. In 1931 she and Rosemary Hume set up a cookery school in London as they had both trained in Paris. They had a flat in Chelsea and they would reputedly serve their students creations to passing trade at chairs and tables on the pavement. Lucas is thought to have helped Hume create her first cookery book as Hume's spelling was known to be poor.
Lucas worked as a hotel chef in Hamburg before World War II and later claimed that Adolf Hitler often dined there and had a taste for stuffed squab. She later opened a Cordon Bleu restaurant and a cooking school in New York. She also ran the Egg Basket restaurant by Bloomingdale's in New York. One of the earliest television cook-show hosts, Lucas's To The Queen's Taste was broadcast on CBS in 1948-1949 from the restaurant. She had another show in the 1950s.
Dione Lucas was the first woman featured in a cooking show on television on WPIX-11 in New York. In one of her New York restaurants, The Gingerman, Lucas helped to introduce the omelette to the American palate. She can be seen as a predecessor and influence to Julia Child. Dione Lucas authored several cookbooks on French cuisine.
