Description

      The present invention relates to a gripping tool with a magnet that can be easily held by foreigners who do not have a chopsticks food culture, those who do not have strong fingertips, and who are not good at using chopsticks.

Traditionally, chopsticks were generally two sticks that could not be used well without practice to some extent.
In addition, when not in use, a pair of chopsticks are joined at the end of the handle (see Patent Document 1), magnetized at the center of the handle (see Patent Document 2), and not eaten too much when eating. In addition, as a device for intentionally making it difficult to use, a prior art (see Patent Document 3) in which a magnet is provided at the end on the handle side is also known. All of the chopsticks disclosed in these documents are provided with a magnet in a part in the longitudinal direction, and temporarily maintain contact with each other.
