PURPOSE: To provide a cutting tool by which a material to be cut is cut in its state being sandwiched.

CONSTITUTION: Heat resisting rubber boards 8, 9 are respectively fixed on the upper faces of the fixed blade 1 and the movable blade 2 of a pair of shears for cutting fruit, the rubber board 8 is made to project from a blade tip 3 to the blade tip 4 side of the movable blade 2, and the rubber board 9 is made to project from the blade tip 4 to the blade tip 3 side of the fixed blade 1. In the case of recovering Si single crystal obtained by CZ method, the use of the shears enables to cut a seed processing part 32, while a part of the seed pressing part sandwiched so that safe and reliable recovery works of Si single crystal can be performed without any trouble such as bounce of a wire for pulling up Si single crystal.
