Created by Mikiya Kobayashi, the chopsticks feature a clever angled design at the tip, so when not in use, the end that touches your food never comes into contact with the table. It’s a brilliantly simple improvement to the chopstick design that unfortunately also seems easy to copy. So even though they’re $US15 a pair, it’s probably best to buy the real deal to support the clever designer who came up with the idea — before ripoffs show up in every restaurant from here to Wagga.
seems easy to knock over
Almost every pair of chopsticks I've used has had this "feature" by way of the fact that the held end has a much larger diameter than the food end.
Unless I am missing something not so obvious, I don't see the big deal here.
