Any blades w/o PTFE coating?

[ErkRusselReserve]

Title says it all. Are there any blades w/o PTFE coating? Plastic going direct into the body via micro cuts is a potential concern. Can it be avoided?

Straights? Yes.
Black Beauties???

Anything else?

I think lord brand makes a stainless uncoated, maybe personna too. There's probably more but that is just the top of my head .

PTFE is inert, unless heated to well over 500F it's a heavy, long chain polymer. The danger is from the monomers (PFAS, or more properly perfluoro alkanes) that are the issue.

I suspect PTFE is ubiquitous on blades, it makes a very large difference in the perception of sharpness. I don't know for sure, but I'd expect it to be sputtered on just like the various metal coatings.

Teflon is the DuPont trade name for PTFE, I think the chemical name is poly trifluoro ethylene but I could be wrong.
