Why do metal cooking utensils often have plastic coatings on their handles?

The reason metal cooking utensils often have plastic coatings on their handles is that plastic effectively reduces the transfer of thermal energy to the hands. Metals are excellent conductors of heat, meaning they quickly absorb and transfer heat from hot surfaces to the hands, which can lead to burns or discomfort while cooking.

By using plastic for the handles, the heat transfer is significantly diminished, allowing users to maintain a comfortable grip on the utensil without the risk of burning themselves. This design feature enhances safety and usability while cooking, particularly for utensils that are often in direct contact with heat sources.

While other materials may have their benefits, the primary purpose of the plastic handle is to provide a safe and effective barrier against heat conduction.
