Abstract:
Razors are described herein. In some instances the razors include a safety razor blade unit comprising a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap. A first blade defines a blade edge nearer the guard and a second blade defines a blade edge nearer the cap. The first blade has a cutter force greater than the cutter force of the second blade. In some instances the razors provide a comfortable shave having improved closeness.

Abstract:
Multi-blade razors are provided, having blades with differing properties. In one aspect, a razor is provided that includes a safety razor blade unit comprising a guard, a cap, and first, second and third blades with parallel sharpened edges located between the guard and cap with the first blade closest to the cap, the third blade furthest from the cap, and the second blade disposed between the first and third blades, the blades having first, second and third tip radii, respectively, at least two of the three blades having different tip radii, and at least two of the blades having different coefficients of friction.

Abstract:
A razor having a housing, a guard located at a front of the housing and a cap located at a rear of the housing. A skin contact plane is tangential to the guard and the cap. A blade couplet is disposed in the housing, the blade couplet being formed of a leading blade having a leading edge and a trailing blade having a trailing edge, both edges being directed towards the front of the housing and the leading blade being positioned between the guard and the trailing blade. There is a span of about 25 μm to about 850 μm between the leading edge and the trailing edge, the leading edge has an exposure of about 25 μm to about 500 μm below the skin contact plane, the trailing edge is positioned in line with or above the leading edge and has an exposure of about 150 μm above the skin contact plane to about 300 μm below the skin contact plane, and the difference in exposure between the leading edge and the trailing edge is equal to or less than the span between the leading edge and the trailing edge.
