Culinary Knife Skills (CKS)

So I have a set of shun knives.  Its been about a year and a half and they seem to be to the point they need to be resharpened.  I don't have a stone set to do it myself and someone told me that shun will sharpen their knives for free if you send them in.  I would prefer to not spend the money on a stone set right now.  So question is can I send it to shun?  can I take it to a local sharpener (or would they not know what they were dealing with?)  my wife is a stylist and has a guy who does her scissors and he claims to do knives.  Suggestions?
