Traditionally fireplace tongs had only two opposing prongs just like touching your thumb and forefinger together. The problem is a log, particularly a good size one, tends to twist out of control.
Pilgrim’s fireplace tongs all use a three prong setup, which grasps the log firmly with little pressure and give you complete control when you are moving or adding logs to the fire. Once you try it, you’ll never to back to the old two prong type.
