this shit happens; best bet ist to let it dry out very well, perhaps heat the ski a bit with a wax iron, then clean the part where the edge has ripped out and fill it with epoxy.then let it harden out for a time ( at least a day) then take a dremel or sharp knife and trim off any excess epoxy.
You might want to round off the epoxy around the edge so it doesnt catch any steel or ice and chip or break off...
if you're not comfortable with doing it yourself, bring it to the shop!but don't expect any miracles, i don't think they'll put in a new edge....
