- 5. A cutting tool according to claim 1 including means for varying the voltage across said cutting edges.
- 6. A cutting tool according to claim 1, wherein said blades are configured in mirror-image to produce equally opposing side forces which press said blades together.
- 7. A cutting tool according to claim 1, wherein said cutting edges comprise a pair of wedges which are oriented to define a single unit.
- 8. A cutting tool according to claim 7, wherein said wedges are relatively displaceable in directions perpendicular to the direction of cut.
