I have a Saluki greyhoundy lurcher who is terrible to nail clip and also has the extra strong saluki nails which never wear down. After spending years and years doing desensitisation, trying files, dremels etc we came to the conclusion that it was better to just get on with the job, so now every two weeks we put his muzzle on, and hold him tight to get it done in a couple of minutes. Take his muzzle off and a treat and he's fine - he just hates his paws being held (he had his dew claws removed as a puppy before he was rescued and we think it was that).
@FazedNotPhased the quick grows as long as the nails so you have to take that tiny bit off every week to push the quick back. It will shrink back from the nail edge
