The house painter and do-it-yourselfer use a pot opener to lift the lid of the hermetically sealed paint cans to allow air to enter and open the can.
The paint pot opener is a flat metal rod (approx. 10-15 cm) with the end (approx. 1 cm) folded back and thinned for easier access under the lid. The rod then serves as a lever of the first kind. If the end is not folded over, it will be in the shape of a flat screwdriver and / or hook. Slightly shorter models are provided with a ring to put more pressure, sometimes they are combined with a can pierce or a bottleopener. [MOT]
