Should I buy a multitool?
Pliers, wiggling, and a little elbow grease should do the trick.
I’m going to advise against pliers. More metal means potentially damaging the ano on the yoyo. But also, the pressure from squeezing the bearing tightly with them can damage them permanently. I’m going to recommend the yo-tility by Duncan. It had a bearing removal tool, string cutter, and is a great clip for use with a yoyo holster. The holster that comes with it sorta sucks. For a good holster I recommend legyoyo holsters from… Legyoyo on the forums!
