Sea to Summit's AlphaLight Cutlery uses a durable hard-anodised aircraft grade aluminium combined with a sleek-yet-strong shape to create an extremely lightweight utensil. By hard anodising the aluminium it forms a kind of "exoskeleton" so the shape of the utensils can be slimmer and lighter. This hardened shell also encapsulates the aluminium, which eliminates the risk of alloy leaching into food.
