304 Stainless Steel Kitchen Cooking Tongs, 9" and 12" Set of 2 Sturdy Grilling Barbeque Brushed Locking Food Tongs with Ergonomic Grip, Blue

Where were these made?

Hi, do these tongs have a "spring" in them, so while using them they don't "slam" shut. Does that make since? (Not the locking clip part when storing)

is this good for corn on the cob to get out of hot water

Is the spring also made of stainless steel? Because I've had tongs where the spring and surrounding parts inside started to rust.
