Lady Deathstrike's fingernails

What's the deal with her fingernails? And when I say that I mean sometimes she is shown with her adamantium fingernails and other times she is shown as having blade-like fingers (I have a feeling this may be down to the movie as it was around that time she got a make-over and the fingernails became more prominant)

And when it comes down to her fingernails....where are they stored? If they are foot-long and adamantium then she shouldn't be able to bend her hands and fingers....

It's always bothered me that Deathstrike's fingers are usually just presented as flesh colored & extra pointy. If her adamantium talons are always covered by skin, she can't cut anything. We know she lacks adamantium skin because takes plenty of battle damage. Her talons  ought to be a nice shiny silver like adamantium is. That's how I repaint her action figures & lead figurines. It's one of the few things I prefer from X-Men 2 to the comics, although I think Kubert & Adams set a precedent for it.
