Have spent many hours re-gripping clubs since my son was five. Between regular re-gripping and pluging in extensions as he was growing every season, I've tried a couple of methods of grip removal when just extending his junior clubs. I found the best way to salvage a grip is using an air compressor, to blow air into the butt end and expanding the grip away from the tape. There are a number of youtube vids on this method that would be much more instructive. The hook utility blade and the heat gun are the preferred methods if you're replacing an old grip. Some of the new solvents are non-flamable, and IF you use enough, works just fine.
