New continental oval blades were available before 753, as far as when the continental oval blades went out of production, I do not know that they have, nor was I aware that "Google .com" was the final word on fork blade issues. I don't really like the look of the continental oval blades, but if you understand their purpose, they are kind of neat. Also, I like the twin plate crown, and those fork blades, and that crown are a great combination. Dave Tesch
