ABSTRACT:
A cutting process in which a blade under tension is moved relative to a workpiece. The blade has a longitudinally-extending abrasive-holding portion defined by blade material that is softer than the workpiece to be cut and overlies a high tensile strength core. The abrasive-holding portion defines a cutting surface extending between opposite sides of the blade and defining less than one-half the total outer surface of the blade, and abrasive particles are partially embedded into a longitudinally-extending segment of the cutting surface but not into the sides of the blade.
