Koreans traditionally use silver chopsticks (Kamishiro actually used Korean chopsticks during his "La-Men" tasting in that one episode of Kabuto). They take some getting used to, as they're flatter, instead of solid square like plastic or bamboo ones. Is there a "Korea town" where you live Mika?
Personally, I'm just used to the plastic Chinese chopsticks that are predominantly available where I live. I'm not the biggest fan of their wide tips (I'd prefer ones that taper a bit more), but like I said, it's pretty much all that's available. A few Asian stores do sell the ones with the finer tip, but they're really expensive (like, almost $2 for a pair).
