Yup. Burning teflon produces phosgine gas. Which is pretty toxic I hear?

Well, technically, no phosgene (carbonyl chloride), because there's only
Fluorine in PTFE, no Chlorine - you get carbonyl fluoride.
PVC, on the other hand, has plenty of Chlorine.
But there's plenty of other nasty stuff that comes off burning plastic
of all kinds - but it's not huge amounts. Occupational exposure on a
regular basis might be an issue - same thing applies to smoke from rosin
and more modern fluxes.
I think it was more the "cleanliness of cut" is better with modern
spinning knife cutters (whether a single blade spin with your finger, or
a motorized one).
