I think you misread it. I think the FA was saying that there were "cutting edges" in International Coach meaning that the maintenance folks hadn't done a very good job in repairing cabin breakage. That's certainly the more reasonable interpretation
Cheers.
We go out to dinner with the pilots and they tell us these awful things. AA used to be top ranked in maintenance, but the pilots say they are stretching things out as much as they can; cutting back with so much it is shameful
Nothing cutting-edge mentioned. You misread it.
