The benefits of plastic cutlery are that your pots will be safe from scratches and it's very lightweight.
Primus says:
Fork, knife and spoon in BPA-free Tritan® plastic. Feather weight utensils with a strap that keep the pieces organized.
Primus' Lightweight TrailCutlery Tritan is very strong, even for a plastic utensils. It has decent depth to the fork's prongs and the spoon's shovel shape is easy-to-use and nice to eat from.
