The edges of the konkave bearing are quite sharp,will they damage the bearing seat of a yoyo?
No. The edges don’t come in contact with the seat. If they did the bearing wouldn’t spin.
thank you…I asked such a dumb question =.=
It’s not a dumb question. It’s far better you ask and learn than be left not knowing.
No problem. And studio’s right, not a dumb question at all.
