Hammer tongs are great when dedicated to handling natural hookah coals. With a 20cm length, it will allow you to comfortably handle your coal cubes without taking the risk of burning yourself, and prevent you from approaching the heat source too closely.
Hammer tongs are also provided with a hammer in the lower part. The hammer is intended to allow you to break your natural coal cubes (e.g. coco cubes) into smaller pieces. Ideal especially for hookah bars that have large amounts of coal to crumble, the Hammer tongs are provided with a protective cover.
Remember that coal must be broken AFTER being heated. It will always be easier to cut a burning coal than trying to split a dry hookah coal! Heat your coals first, and then break it up!
