You can get this set of collapsible chopsticks for $30. The stainless steel upper section is hollow. Pop the top off and slide the white ash lower section out. The wooden tip screws into the upper section using all brass hardware. That might look a little cool, for 30 bucks I can get a lot of disposable chopsticks in my bag. More pictures after the jump.
