That depends on which item. Our long handles (on our fry pans, saucepans, and sauté pan) are made of a hollow stainless steel handle. This allows for the heat to disperse over a greater surface area, so as you move away from the handle base the handle gets cooler. For the items with long handles (saucepans, fry pans, sauté pans), you can generally grab the long handle without a glove or towel under normal operating conditions.
Our “helper handles” on our stock pots and sauté pan are designed for a low profile in order to stack better, so they do not disperse heat as well as the long handle. We recommend using a protective layer between you and our helper handles.
