A first and second blade assembly each have a cutting edge oriented to shave in the same direction. The first and second blade assemblies are each displaceable along a respective first and second path substantially parallel to their cutting edge. First and second linkages couple together a first ends and second ends respectively of the first and second blade assembly. The linkages are configured such that a displacement of the first blade assembly in a first direction along the first path causes a displacement of the second blade assembly in an opposite direction along the second path. Other embodiments are also described and claimed. ## Claims ### Claim 1 A shaving razor comprising: a first blade assembly having a first razor blade with a first cutting edge, the first blade assembly displaceable along a first path substantially parallel to the first cutting edge; a second blade assembly having a second razor blade with a second cutting edge, the second blade assembly deployed to cut in a same direction as the first blade assembly and to be displaceable along a second path substantially parallel to the second cutting edge; a first linkage coupling together a first end of the first blade assembly with a first end of the second blade assembly; and a second linkage coupling together a second end of the first blade assembly with a second end of the second blade assembly; wherein the first and second linkages are configured such that a displacement of the first blade assembly in a first direction along the first path causes a displacement of the second blade assembly in an opposite direction along the second path. ### Claim 2 (depends on 1) The shaving razor of claim 1 further comprising: a third blade assembly having a third razor blade with a third cutting edge, the third blade assembly deployed for cutting in the same direction as the first and second blade assemblies and being displaceable along a third path substantially parallel to the third cutting edge; and wherein a first end of the third blade assembly is coupled to the first linkage and a second end of the third blade assembly is coupled to the second linkage; and wherein the first and second linkages are configured such that the displacement of the first blade assembly along the first path in the first direction causes a displacement of the third blade assembly along the third path in a same direction as one of the first blade assembly and the second blade assembly. ### Claim 3 (depends on 1) The shaving razor of claim 1 further comprising: a handle; and an actuator coupled to the handle to displace the first blade assembly. ### Claim 4 (depends on 3) The shaving razor of claim 3 wherein the actuator comprises: a voice coil. ### Claim 5 (depends on 4) The shaving razor of claim 4 wherein a change in direction of magnetic flux in the voice coil limits relative displacement between the blade assemblies in the first and second paths to be in a range from 0.1 mm to no more than 0.5 mm. ### Claim 6 (depends on 1) The shaving razor of claim 1 wherein an amplitude of the displacement in the first direction is substantially equal to an amplitude of the displacement in the opposite direction. ### Claim 7 (depends on 1) The shaving razor of claim 1 wherein amplitudes of the displacements are in a range of 0.1 to 0.5 mm. ### Claim 8 (depends on 1) The shaving razor of claim 1 wherein the first and second blade assemblies reside centrally aligned in a rest position when no force is applied and are, in use, displaced in a range of 0.05 mm to 0.25 mm in either of the first or the opposite direction from the rest position.
