Replying to Questions about da skis

so im buying a pair of 2006/2007 K2 Fugatives for 75 bucks form my friend( bindings included) and I went to check them out today and they were in half decent shape, like the topsheet is scratched and jazz, but it was looking that bad, except for on each ski, in the same spot below the binding on the edge, the metal was gone and it was the core of the ski? i was told it isn't a big deal when your skiing( my friend didnt tell em this, someone else did) and it probbaly isnt a big deal, but is it fixable and will it affect my skis long term?
