The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
I think it could be both, depending on how much damage they do. Like if they do the amount of damage you'd expect nails to do, relatively superficial unless they hit a vulnerable spot like an eye, that'd probably be Femme Fatalons and Combat Pragmatist (and Eye Scream in this example). If they leave grievous, bloody wounds or cut through durable materials like drywall or concrete, then you'd be getting more into Femme Fatalons that also count as Wolverine Claws.
According to Femme Fatalons, "Weapons like clawed gloves, or clawlike extensions attached to (or growing out of) the hand or fingers are not Femme Fatalons; they're Wolverine Claws. An easy rule of thumb to follow is that if they're primarily for looks, they're Femme Fatalons. If they're primarily intended as weapons, they're Wolverine Claws."
Wolverine Claws seems to be about artificial claws attached to the hands. But what if someone uses their actual, long fingernails as claws to attack with? Which trope is it?
