This is very sad. I think one side of my biND is eating up my strings. I took it apart and all along the “wall” I say that because it’s basically non existent, there seems to be little bumps almost. Like if you were to roll a yo-yo across a street. But just very small. How can I fix this. I really love this yo-yo so I’m skeptical about doing any mods. @YoYoExpertGarrett @codinghorror

Buff that side with a polishing cloth or rough denim.

Hmm that looks like a manufacturing issue, you might want to return it for replacement?

I’m with you @codinghorror that seems like a flaw (not that I know yo-yos but) if the other side don’t have it it could be a flaw that accidentally got through.
