Hi NormK and speedy,
that has worn to a jagged edge that looks like it could shred the cord. I know with the cup starters you could get replacement grommets or a nylon add on over the top as seen below..
I had to throw away an otherwise perfectly fine PT starter because the collar where the cord exits was an early built in non replaceable one that had worn in one spot and was binding the cord.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
