HexClad started in Los Angeles in 2016 with a fairly narrow idea: a pan should behave like stainless steel when you want a sear, and like a nonstick pan when you want an egg to slide out. Most cookware forces a choice between the two.
The brand's answer is a three-layer clad body — stainless steel on the cooking face, an aluminium core, stainless steel on the base — with a PTFE nonstick coating applied on top of the cooking face and then laser-etched into a hexagonal pattern. The etching cuts through the coating and exposes the stainless ridges underneath, so the cooking surface becomes a grid of alternating materials: soft nonstick inside each hexagon, hard steel along every border.
That single structural decision explains almost everything else about the pan — why metal utensils are tolerated, why the surface survives a dishwasher, and why it takes a little longer to heat than a thin nonstick skillet.
