Inspired my your question I hit the wiki hole last night.
I'd never noticed the differences before (rarely go to Chinese places, and foodhall-type places use the same wooden disposables I'd noticed were smaller than my chopsticks at home (the top on the wiki image) that I hate.

I assumed the disposables were short because they were cheaper.

I prefer the disposables. I have some plastic lightsabre chopsticks that are useless.

I'm pretty bad at chopsticks, especially with rice.
But I am charmed to know there is a vulcan grip.
