Abstract: A safety razor unit including a guard, a cap, and a group of first, second, and third blades with parallel sharpened edges located between the guard and cap, the first blade defining a blade edge nearest the guard having a negative exposure not less than −0.2 mm, and the third blade defines a blade edge nearest the cap having a positive exposure not greater than +0.2 mm.

Abstract: A safety razor blade unit has a guard (2), a cap (3) and three parallel blades (11, 12, 13) mounted between the guard and cap, at least one of the blades, guard and cap being movable from an at rest (non-shaving) position to modify a blade exposure dimension to attain a target blade geometry, at which shaving is initiated, in which the exposure of the first blade (11) is not greater than zero and the exposure of the third blade (13) is not less than zero. At least one of the cap (3) and guard (2) can be movable against the force of a spring (21 or 20) from an at rest position in which all the blades between the guard and cap have their cutting edges disposed below a plane tangential to the skin contacting surfaces of the guard and cap. The blades can be independently sprung or carried for movement in unison on a carrier pivotally mounted in a frame of the blade unit.

Abstract: A safety razor blade unit including a guard, a cap, and a group of first, second, and third blades with parallel sharpened edges located between the guard and cap, the blades being resiliently movably mounted and having an at rest condition in which the first blade defines a blade edge nearest the guard having a negative exposure between about −0.04 mm and about −0.06 mm, the third blade defines a blade edge nearest the cap having a positive exposure between about +0.04 mm and about +0.06 mm, and the second blade defines a blade edge having an exposure of about zero.

Abstract: A safety razor blade unit including a guard, a cap, and a group of three blades with parallel sharpened edges located between the guard and cap, the first blade defining a blade edge nearest the guard having a negative exposure not less than −0.2 mm, and the third blade defining a blade edge nearest the cap having a positive exposure of not greater than +0.2 mm, the second blade defining a blade edge having an exposure not less than the exposure of the first blade and not greater than the exposure of the third blade.

Abstract: A shaving system including a handle, a container and a plurality of blade cartridges accommodated in the container. The handle is selectively engageable and disengageable with said cartridges. A guide is provided to enable the handle to pass over a plurality of cartridges in a row in the container and to engage only the last cartridge in the row.

Abstract: A shaving unit having blade means exposed forwardly of an overlying cap member and rearwardly of a guard member, wherein the blade means and guard member are movable in unison and relative to the cap means against a resilient restoring force in response to forces transmitted to the unit during a shaving operation, to alter the shaving geometry of the unit.
