A hinged sheet utensil folds flat for packaging, then fastens into a spoon, fork, or knife form without complex switching.

A comb-like retaining block stores cutlery in overlapping single-layer slots, enabling compact storage and individual removal without contamination.

Hygroscopic filler holds effervescent tablets inside the straw to prevent premature dissolution, reduce foaming, and extend fizzy flavor delivery.

A cage handle with a replaceable fluid bag and internal passages dispenses condiments at the fork prongs with controlled flow and easy changes.

Rotating cutting tines and a spring-driven handle let one utensil spear and cut food safely for users with limited upper-limb function.

Flexible radial grippers and pivoted handles grasp irregular chips with less breakage, faster serving, and cleaner portion control.

A hinged upper member lets one utensil switch between fork-like piercing and chopstick-like grasping, scooping, and cutting.

A nested retractable chopstick with a locking slot structure improves portability, cleanliness, and reuse without separate storage.
