What's the advantage of tri-ply?
Tri-ply means that there is an aluminum core bound between two pieces of stainless steel. The advantage is that the cookware heats up very quickly on all sides rather than just the bottom of a pan. This allows you to cook food to cook more evenly than other cookware sets.
And I bought this set yesterday. It looks fantastic in person and is a steal at this price and is a Tri-Ply set.
