A system and method of heating a tool with electromagnetic radiation aims to harness the dialectic heating effect of radio waves on metallic nanoparticles to generate controllable, user-safe, highly variable heat with the use of a specific supporting structure. It is considered that the method may be applied to a variety of existing assemblies, such as a knife, a cooking pot, a jacket, and other embodiments. The system of the present invention provides at least one tool body, at least one suspension mechanism, and a plurality of photothermal particles. Furthermore, at least one portable electromagnetic (EM) wave generator is provided, wherein the portable EM wave generator either is integrated into the tool body, or is positioned adjacent to the tool body, wherein the portable EM wave generator includes a manual on/off switch. The overall process allows for controlled generation of heat within a variety of physical objects.
