ABSTRACT:
An improved blade for cutting and stripping insulation from insulated electrical conductors has a cutting edge with a circular cross-section when viewed in the direction parallel to the axis of the insulated conductor to be stripped instead of the elliptical cutting edge of conventional blades. The blade is manufactured by feeding a manufacturing tool through a blank so as to generate a curved surface having a longitudinal axis connecting the blank faces at an angle thereto. The curved surface has an elliptical contour when viewed along the axis.
