Shape-Memory Polymer Handle Cutlery The handles of this cutlery are made of shape-memory polymer, allowing them to be reshaped repeatedly to fit the user's hand. By placing the handle in hot water (70°C or higher) for about 5 minutes, the handle will become rubbery. You can then slowly bend and twist it to create a comfortable shape. (The head part also rotates, so adjust the angle as well.) Once you've achieved the desired shape, place it in cold water to harden it into a plastic-like form.
