Can this be possible ?
Has anyone tried this ?
If it was possible how would I do it ?

Also, would anything happen if I sand the little metal circle thing on the new breed when it doesnt have caps ? The reason why is because i want to smooth it out so i can like try to do weird things with it, its hard to explain.

Why would you? Just get a PGM. Save yourself from destroying a perfectly good yoyo.

The little metal circle thing (I’m assuming) is the solid spin axle system. I wouldn’t mess with it if I were you. The New Breed is an amazing yoyo stock. Go play with it.
