There isn't much to say about a sturdy set of tongs. They're indespensible for grilling, and when you don't have a pair, it is painfully obvious.
These OXO Good Grips Grilling Turners fit the bill. They're sturdy and built with rust-resistant stainless steel. They're 16" long so they keep your mits away from the flame, and they lock for easy storage.
At $15 these tongs won't break the bank, and have received a high 4.7/5 stars from nearly 180 reviewers.
