I have one bicycle frame made entirely out of carbon fiber. It climbs well as it is very light. It is very comfortable to ride as well so it's also great for long distance rides. The extra cost of CB is justified, although CF can crack and break easily if not careful.
Now, what these CF chopsticks do for me is the question I have.....They are cool looking after all.
Will my arm never tire from using these thus allowing me to continually feed myself for many hours?
Or would I earn some cool points with the sushi chef if I took them with me?
