Methods of cutting and stripping insulation and other coverings from electrical wires, optical cables, and the like, using one or more blades while protecting the wire from undesired scoring or nicking. In one embodiment, two or more blades are moved radially inwardly to cut the insulation to a desired depth, close to the wire, and then moved apart by a short distance before being moved axially to strip the insulation. In a second embodiment, the blades are moved toward one another to cut the insulation to the desired depth, then moved apart by a distance greater than the depth of cut, moved axially by a distance less than the length of the cut, moved toward one another to grip or pinch the insulation and again moved axially to sever and strip the slug of insulation. In a third embodiment a pair of gripper members engage the insulation as the blade or blades cut to the desired depth and strip the slug off the conductor after movement of the blade(s) out of engagement therewith.

A method of cutting a layer of insulation covering an electrical or optical conductor, said method comprising: (a) positioning and holding a linear portion of said insulation-covered conductor in a first, fixed position on a predetermined axis; (b) positioning the cutting edges of at least two cutter blades in spaced relation at radial distances from said axis great enough to permit said insulation-covered conductor to pass through the space between said edges; (c) moving said cutting edges simultaneously in directions both transversely and radially inwardly with respect to said axis to a first position wherein said cutting edges each extend into said insulation and are spaced from said conductor by first, predetermined distances; (d) stopping said transverse movement and moving said edges simultaneously radially inwardly with respect to said axis to a second position wherein said edges are spaced from said conductor by second, predetermined distances.
