Maybe true for bare open-grain wood

like oak or even ash, but for rubbing out varnish, there's really little risk of leaving broken-off fibers. Bronze wool is an alternative or a Scotchbrite pad, but the grit grades in nylon pads are uneven and I've found too agressive for rubbing out finish. Graded pumice or rottenstone works well, too, but they're cumbersome to use on small shapes like canoe trim.
