PROBLEM TO BE SOLVED: To provide a compact lid opening tool capable of easily opening a lid.SOLUTION: The lid opening tool 1 comprises a plurality of cutting blades 32 for press-cutting and opening a lid, and a cutter pedestal 31 for installing the plurality of cutting blades. The plurality of cutting blades consist of cutting blades 32a, 32b having two or more kinds of projection height positions. Thus, the projection height positions of the plurality of cutting blades for press-cutting the lid have at least two kinds, and the number of the cutting blades firstly brought into contact with the lid when press-cutting the lid is smaller than the total number of the cutting blades, and the force to be applied to one cutting blade is increased more than that when all the cutting blades are simultaneously brought into contact with the lid, and the lid opening tool can easily press-cut the lid. |
