99.9% of the time we take out grips with an Exacto blade. We slip the blade in between the grip and the hole, usually in the top of the hole (farthest from thumb hole) because most pro shops do not glue that area, and then slowly, but firmly, wiggle the Exacto blade around the hole. When you get to a glue spot, we usually have to apply more pressure and or use a little bit of sawing action to get the grip cut. Like i said, 99.9% of the time this works.
If who ever installed your grips the first time around is a hack and doesnt know what to do and they put glue around the hole (from top of grip to bottom of grip) then you have to do a little more. Usually in this case i we have troublt cutting the glue because it is deep and hte exacto blade isnt long enough, so we just go at it with a flat head screw driver and try to pry it out. Once we get it out we have large chunks of grips and glue left on the hole. To get that out we would use 1 of 2 things. First we would take the exacto blade and slowly go and hack away at it until most of it is gone. If that dosent work, or the glue is too deep, the alternative is to hack at it with a Bevel Knife which is much longer.
If all else fails...take it to a pro shop, have them do it for you, and then watch them and watch what they do to remove it. If at this point u cant get it out yourself, then it might need to be redrilled, which in the 3 years of pro shop experience i have, i have had to do maybe 2 times.
