Not alot YOU can do, but a shop can often replace the entire edge, however, that can be pricey.
You can cut out the section that is sticking out, buy some high grade epoxy or contact cement, and fill in where you are missing the edge. This wont be a permanent fix- the epoxy will crack and fall out on occasion, so you may be best to ride another set of skis, and keep those for handrails/and or backyard skiing.
