First while it's bent out like that file it lightly, this will soften the new corners on the crack and help prevent them from grabbing and ripping out a section of edge.
Mix some epoxy up, make it a little thinner than usual if you can, you want it to really work it's way in there. Get as much as you can in between the edge and sidewall, and ideally between the sidewall and core. A disposable syringe (without a needle!!!) can work well for this... and will make the person you buy it from think you're a junkie.
Then get something smooth and flat, put it hard up against the edge and give it a couple of smacks with a hammer to try and flatten out that edge. A piece of steel flat stock works well if you have any around.
Then clamp the hell out of it both vertically and horizontally. Put a heat lamp on it for half an hour or so if you have one to help the epoxy cure.
Then cross your fingers and go ski them.
