Do yourself a favor, and bring a pair of all-metal stainless steel tongs with you when you go camping. Any plastic or silicon grip add-ons to the tongs will only get in the way, and could possibly melt around the campfire, add unnecessary weight, and make cleaning the tongs more difficult.
A 14″ to 16″ pair keeps your hands well away from the fire, lets you flip food like a pro, and allows you to quickly adjust the coals in the fire-pit (baked potatoes anyone?)
I recommend self locking tongs (as pictured) that have been stamped out of a heavier duty gauge steel. Sometimes you get lucky and the locking mechanism contains a hole in it so you can hang them off a nail. The dollar store ones are typically too flimsy. Cheap ones lock with a sliding square ring, that will eventually slip off and get lost.
You will inevitably use the tongs as a poking stick to re-arrange the logs on the campfire, so don’t cheap out on this tool as it needs to be sturdy enough to handle everything you want to pick up.
