I reject the underlying premise of this thread: that is the existence a "hot chemist girl." One of my college roommates was a chemistry major; there were no, zero, none, nada hot chemist girls to be found. Those boys would get a stiffy if left alone in a room with a upended string-mop, they were so desperate for anything vaguely resembling female companionship.
Carry on,
rats...
My degree is in chemistry, I work as a materials engineer, and as part of a previous job I did hazard assessments for the chemicals we were using so that I could prescribe the correct protective gear (PPE).
The elements the lady mentioned are, of course, in our knives. They are also bound in the alloy and are not transferred to the food.
So there is no exposure. So you may use your knives.
As mentioned above, the various metals in the alloy are bonded to one another and pretty much don't react with the food.
The only reason I prefer stainless at all is that they tend, on the whole, to impart less arbitrary metalic taste to the foods.
I've actually considered getting a couple of ceramic blades for that reason.
Toxic? Nah.
