It is common to be removed. The conventional tongs are often made of metal, and in addition, plastic ones or those using natural materials such as wood or bamboo are used.

  Metal tongs are excellent in terms of service life and strength, but since the force tends to concentrate on the tong tip portion sandwiching food, the tip portion may be damaged or scratched by metal fatigue. Since the missing metal pieces are small, it is difficult to tell if they are mixed in food. For this reason, food containing metal pieces may be eaten as it is, which is dangerous. Further, the plating portion may be lost due to scratches generated at the tip portion, and metal rust may occur. In this case, there is a problem of adversely affecting the taste of food.

  Plastic tongs and tongs made of natural materials such as wood and bamboo are inferior to metals in terms of service life and strength, but have strengths that can be used repeatedly, compared to metal products It can be manufactured at low cost. However, plastic tongs are easily damaged by lines, and in particular, germs are likely to grow on the line wounds at the tip of the tongs that sandwich food, and are easily deteriorated. Therefore, in the case of tongs composed of these materials, foreign matter may be mixed into the handled food due to deterioration cracking during use. In particular, in the case of tongs using natural materials, it is necessary to sufficiently wash and dry after washing, and if the care after use is insufficient, miscellaneous bacteria will easily propagate and mold will easily occur, etc. There is a problem that caution is required for hygiene.
