In all my decades of using chopsticks, I've never had a splinter poke me. But I've seen people rub their chopsticks then complain about splinters.
But the internet informs me that the composite chopsticks that I am used to seeing went away during covid and now disposable wooden chopsticks are the norm.
I almost associate the cheapo reusable plastic chopsticks with some food courts or Matsuya at this point.
