While on the go, one can bring with them a pair of one-off chopsticks in a box.
After use, one can sharpen the chopsticks just like sharpening a pencil.
The sharpening process cleans the chopsticks and therefore can be re-used.
The life of one-off chopsticks can be lengthened through this innovative design of a chopsticksharpener.
