To provide metal cutting scissors that can cross a fold to freely cut a square corrugated plate regardless of the spacing and depth of recesses and projections of the square corrugated plate.

A stationary blade piece 11 includes a stationary blade fixing part 21 at the distal end of a stationary blade handle 22, and the stationary blade fixing part 21 is provided with a stationary blade 21c. A moving blade piece 12 includes a moving blade fixing part 31 at the distal end of a moving blade handle 32, and the moving blade fixing part 31 is provided with a moving blade 31c. The stationary blade piece 11 and the moving blade piece 12 are fitted rotatably around a pivot 13 at an intermediate part of the stationary blade handle 22 and at an intermediate part of the moving blade handle 32, and cutting can be performed between the stationary blade 21c and the moving blade 31c. The stationary blade fixing part 21 at the distal end of the stationary blade handle 22 is arranged on the back side rather than a blade line 21f of the stationary blade 21c and an extension line of the blade line 21f, and the rear end is arranged on the moving blade piece 12 side on the opposite side to the extension surface of a split surface 21h of the stationary blade 21c through the back side rather than the extension line of the blade line 21f between a pivot 13 and the stationary blade 21c.
