Oh yea I can use them with great ease, love them. I wanted to use them ever since I can remember, first seeing an asian eat with them. I thought cool, how amazing is that to be able to eat food with 2 twigs. When I was in my early teens, I read a book on how to use them, which helped only a little, so I would watch asians using them and became much better. Then when I came to Japan for my first visit, everyone was quite surprised at how well I could use them. My biggest shock or whatever was my second trip here and my host mother turned around and said I can use chopsticks better than her 19 year old son, I was like OOKAAYY. Now its at the point if I'm eating out, some Japanese people will be staring at me then say to their friends "sh*t that foreigner uses chopsticks better than me" I kinda like that.
Not sure if you know that you can even use chopsticks to cut certain foods and meat into smaller pieces if they're too big?
There is even a book on the history of chopsticks, how they were invented as such, as well as the do's and don'ts.
