Abstract
An extended-life cutting blade is adapted for mounting on a hand-held cutting tool in multiple operative orientations. A single cutting blade may provide up to four independent shear edges, each of which has a useful life. The blade can be easily changed from an orientation adapted to cut a workpiece with one shear edge to a different operative orientation adapted to cut with a different shear edge by selecting an appropriate mount on the blade.
