Are you permitted to Break apart the Chopsticks to use them On Shabbos?
Remember to break your chopsticks and open the packaging before Shabbos. Thank you.
Wouldn't it be a clearcut case of "makeh b'patish" (putting the final touch on an object to make it usable)? The chopsticks clearly aren't usable for their intended purpose while they're attached together.
This is Uvda d'Chol, as defined by Mishna Berura 314:48. (his point there about this being Uvda D'Chol when one breaks wood into large pieces is only to avoid Tochein (grinding) and is not a 'shiur'that would absolve to complete chop-sticks)
