Earlier there was a bit of info about F-35C hook being redesigned IMHO to look like an A-4 hook and that the A-4 hook had to be
unsharpened every now and then (depending on what the metal to metal abrasion effect was over time) to prevent what we see in this VF-805 LineBook page highlighting a frayed no.5 wire onboard HMAS Melbourne (which had 5 arrestor wires during the A4G/S2E-G era whereas earlier in the Sea Venom Gannet era there were 6 wires with the sixth ["JC wire"] removed).
I'm sure whatever the result of the F-35C hook redesign that the USN will continue to regularly inspect all aspects of their arrestor gear / hook / aircraft combinations for any maintenance required. Text of signal seen top right of linebook page repeated:
"2. Day
K. 1. During arrested landing, hook penetrated the strands of NO 5 wire, engaging two of the six strands. Although port tyre burst on touch-down, approach and arrestment considered normal. Film of landing showed first point of contact of hook was on or very close to wire"
