Oz, there is a blade, I checked several times to see if the wires were getting any damage. I tried to make sure that the wires were somewhat split so the blade goes between them. Seems to be fine, I can check in a few weeks to verify. But, I don't think there shouldn't be any issue if the wires are solid/snug with no movement then there won't be any chaffing.
Are you thinking of doing this also?
