Replying to Need some advice with my edges

so i was just skiing my PVC boxes earlier with my urban/ backyard designated skis, and about 3 inches of edge ripped out. this doesn't surprise me, i'm not mad by it, i don't want a warranty or anything etc. etc., BUT...

on either side of the ripped out portion of the edge, the edge that is still in is really sharp. it catches on the PVC and there's tons of little gouges in the pipe, maybe 1/16 of an inch deep. not worried about my boxes, but it's like hitting a sticky spot and throws off my balance and makes tricks harder and unpredictable.

anybody else had this problem? any way to fix it?
