ABSTRACT:
A cutting device having a holding element for holding a workpiece, a pair of cutting blades for cutting the workpiece held by the holding element, the cutting blades being adapted to be rotated, a wear amount detecting element for detecting the amount of wear of each of the pair of cutting blades, and a control element. The control element is arranged to selectively cut the workpiece by both of the pair of cutting blades, or cut the workpiece by one of the pair of cutting blades. When the workpiece is to be cut by one of the pair of cutting blades, the control element compares the amounts of wear of the pair of cutting blades detected by the wear amount detecting element, and allows the cutting blade having a smaller amount of wear to cut the workpiece.
