Ah I didn’t see that little spiral graph. I agree with you for anyone who keeps their knives sharp. But if you’re trying to cut thin slices off a roast and have to choose between a bread knife and a dull chef’s knife, I’d likely go for the bread knife. That said, I don’t know they intended it that way, and it totally could have just been an error.
You hear it as a joke when you’re young, but it’s not til you’re old that you realize “you are what you eat” is literal.
