When we found this little tool, we realized we found a winner. This multi tool has almost everything you would want in a yo-yo repair tool. It fits in your pocket. It has a full sized and small Phillips screwdriver. (i've been using the small Phillips screwdriver to knock pogs out of Spintastics and Duncan yo-yos) . It has a large slot screwdriver and a small slot screwdriver (I've been using this small slot screwdriver to get O-rings out of Yo-Yo Jam yo-yos and to help get spacers out of yo-yos when they are stuck). The front of this tool is a surprisingly strong pair of pliers that have found a lot of use in getting things on and off many a yo-yo. Behind the pliers, between the arms is a small wire cutter, that is a serviceable string cutter. The cool thing about this tool is that it does not have a knife edge. This should be allowed to be brought to school by most schools. Of course school rules vary from school to school, so check your local rules.
